CryoView MP

CryoView MP

The Cryoview MP enables measurements of low temperature electrical, optical, magnetic, and thermal propeties of materials fully integrated with near-field and far-field optics, Raman, and fluorescence spectroscopies. It opens new avenues for multiprobe measurements including transport properties of materials at temperatures as low as 10K.  The CryoView MP is an award-winning, must-have tool especially suited to probe 2D materials such as graphene, MoS2, BN, TaS2, NBSe2, WS2, HfO2, metamaterials, and metasurfaces as well as other functional material materials such as Si, carbon nanotubes, III-V semiconductors, and quantum dots.  

Many of these materials with their associated properties require a wide variety of physical phenomena that must be applied for a full functional understanding.  Examples include: nanometric photoconductivity and other optically related properties, nano electrical characteristics (electronic mobility, charge carriers, etc.), thermal properties, and quantum Hall effect.  All these phenomena can be investigated using apertured and scattering modes of NSOM and sSNOM and/or Kelvin probe, which are often coupled with Raman chemical characterization and other optical spectroscopies such as photoluminescence.

True AFM operation for advanced SPM functionality

Up to 4 probes are possible with the CryoView MP where each probe is capable of all SPM modes including magnetic force microscopy (MFM), electrostatic force microscopy (EFM), Kelvin probe force microscopy (KPFM) for low temperature operation.  These advanced modes are possible in addition to topography and morphology with non contact AFM based methods.  Non-contact AFM is made possible through tuning fork actuation where the probe is mounted onto the tuning fork, and feedback is maintained by monitoring either the amplitude, phase or frequency .  

Compatible with any SPM probe including cantilevered probes

Any probe, including cantilevered probes, can be mounted onto the tuning fork for a full range of SPM capabilities at low temperature. All AFM and STM probes are compatible with the CryoView MP.

Complete optical integration of Raman and NSOM functionality

All probes in the CryoView MP have unobstructed access from above and below enabling full integration with optical microscopes and optical methods at low temperature.  With selection of correct probes, AFM-Raman or NSOM can be performed with any of the probes in the system.

Low temperature transport studies

The multiprobe design in the CryoView MP is uniquely suited for electrical, thermal, and optical transport studies.  One probe can be used to excite or optically pump the sample, while a second probe can detect the results of the excitation.  A third and fourth probe can be then be used for further study and characterization.  Numerous examples of transport studies that can be studied with our multiprobe system can be found here including electrical transport on graphene with simultaneous Raman or simultaneous reading and writing of protein features on a sample.


Accomodates upto 3 probes 

Upto 3 probes can be modularly added. Examples of a 1-probe and 2-probe system are shown below.

All modes of NSOM

True Collection Mode

Collection mode NSOM is depicted in the schematic below, where the light illuminates the sample, and then is collected through the NSOM probe by a detector.  The CryoView offers both tip scanning and a sample scanning stage with upto three probes that can scan independently and simultaneously.   A sample scanning stage enables easy and rapid alignment of the sample relative to the illumination source and ensures that the microscope optics are independent of the AFM scanner. This instrumentation design is ideal for true collection mode NSOM.  

For an explanation of all modes of NSOM, please see the NSOM tutorial.

True reflection mode NSOM

In true reflection mode,  light is introduced via the NSOM probe, and then collected by a detector above the probe as shown in the schematic below.  True Reflection mode NSOM is possible on the CryoView due to the use of "transparent", cantilevered probes.   Furthermore,  the design of the Multiview series separates the  excitation and collection paths so that they don't affect each other, thus enabling true reflection mode NSOM measurements to be conducted.  Other designs that take advantage of straight probes or apertured Si probes are significantly more challenging for true reflection mode.

-For an explanation of all the different modes of NSOM, including transmission, reflection, collection, and illumination modes, please see the NSOM tutorial page.

Dual Configuration for Optical Pump/Probe NSOM experiments

Optical pump/probe experiments can now be performed using one probe to optically pump while the other probe measures the optical output in a variety of configurations.  In the example below using two cantilever, near-field optical probes with exposed tips, light is injected through one probe and is guided through the sample which is a fiber.  With the second probe in place, this injected light can be collected and analyzed both spatially and temporally.   In this image two NSOM probes are seen in AFM contact with the input and output of the fiber waveguide.


Cantilevered probes for the best NSOM performance

Nanonics is the global pioneer in glass probe manufacturing and has developed a whole suite of probes for all your NSOM applications in our Nanotoolkit that are compatible with the Multiview 2000 system, featuring glass cantilevered normal force probes for high-quality imaging of all samples, efficient apertureless NSOM probes, fiber probes with metallic nanoparticles in tip, metallized probes, and straight probes also available for shear force feedback measurements 

Completely flexible optical access designed for NSOM operation

This enables total flexibility in your NSOM setup, as the CryoView can be integrated with any optical microscope.  Additionally, total optical access to sample and probe position from above is possible since the cantilever probe/scanner assembly does not obscure access


Tuning fork feedback without Raman laser interference 

The CryoView is equipped with a laser-free feedback method called normal force tuning fork feedback. For example, many SPM laser-based feedback systems employ red lasers, which would then interfere with the Raman emission in the redo from the sample. The CryoView MP gets rid of all problems associated with optical interference in your Raman experiments.

Effortless AFM and Raman integration

No modification of the Raman path is necessary to accomodate the SPM tip and head.  This design results in a natural and straightforward Raman path for integration without the need for tilting or bending the Raman path to accomodate the SPM. Furthermore, transparent optical AFM probes provide a completely transparent optical system. Both reflection Raman and transmission Raman are standard on the CryoView.  Side illumination is also available. This system is compatible with 50x, NA 0.42 optical objective from the top and from the bottom.

Built for TERS operation

Quick and easy TERS hotspot detection

Detection: Combined tip and sample scanning stage within the same scanning system provides accurate positioning of the probe at the ideal location for TERS with respect to the focused laser spot.  Tip can be positioned within the center of the Raman hotspot for optimal TERS signal detection

Sample can be imaged with the sample scanning piezo stage without losing the TERS hotspot position.

     All modes of TERS including STM and AFM-TERS with easy interchangeability are available. Thus the same probe (either conducting or with a conductive coating for STM-based feedback) can operate in AFM feedback using tuning fork based feedback for TERS measurements, and then it can be switched to tunneling based feedback for TERS operation in gap mode.

    TERS on non-conducting surfaces

   Availability of the upper XYZ piezo scanner for the tip scanning enables 3 point TERS measurements for comparing the difference between enhanced and non-enhanced spectra and extracting new information.

STM and non-STM TERS probes

Gold and silver-coated AFM probes

Nanonics TERS probes are supplied bent in the range of 45-60 degrees, the optimal angle for TERS excitation

Autofocus for superior Raman resolution 

The CryoView MP provides autofocusing onto the sample at every pixel point. Thus for rough samples, tilted samples, or samples with unusual Z variation, the CryoView MP provides the best Raman resolution as it makes sure to have the sample in focus at every point a Raman spectrum is collected

AFM with Most Open Optical Architecture for Multiaxis Raman configuration

The CryoView can be combined with either an upright, inverted, or a dual microscope (combined upright and inverted) where the same SPM head is used for either microscope configurations.   The CryoView with dual microscope can be integrated with many types of the Raman spectrometers.  Such a system enables Raman and TERS measurements to be conducted in upright, inverted, and side-illumination microscope configurations.
