Chlorine Gas Nanolithography

Etching of Chrome Film with Free Chlorine Radical 
 

 
4.5 X 4.5 micron image of Chorine line etched onto chrome film


Protein printing is made possible by the Nanonics Chemical Delivery System and Nanopipette

 

Only Nanonics can deliver chemicals or gas onto the sample on line, with no need to remove the tip from the sample.

AFM Thermo Resistive Nanonics Probe

 

 In the Dual Wire Thermo-Resistance probe, two platinum wires are stretched through the nanopipette and fused together at their tips. This fused junction has a resistance that is temperature-dependent. This unique tip allows simultaneous measurement of surface topography and thermal conductivity

 
Scanning Thermal Microscopy (SThM) for quantitatively investigating the heat dissipation characteristics in substrate-supported andsuspended (with asymmetric type of contacts) current-carrying GaN nanowires with diameters of4060 nm, where the phonon confinement is expected to play an important role in thermal transport.

(a) Schematics of the SThM experiments; (b) ac and (c) dc SThM images with the inset to (b) showing the measured Vth (solid circles) as a function of Vrms and the parabolic fitting (dashed line); (d) SThM images showing the "double-line"-like structure and (e) the corresponding profile across the nanowire; (f) SThM image obtained in vacuum (106 Torr); (g) profiles of ambient and vacuum SThM images taken perpendicular to the nanowire.

Nano Optical and Thermal SPM

 
 
The MultiView 4000TM System simplifies the task of optically and thermally profiling on-line an optoelectronic device. Seen in these images (above) are the optical distribution of light in a quantum wire laser (NSOM) and the thermal distribution around the laser. The image below includes the p contact region in the thermal image. As can be seen, the thermal and light distribution bear no correlation to one another, but rather the thermal distribution is bowed towards the p contact where electrical charge is injected.

  • Ultrastable solid wire electrical probes q Ultra-Sensitive Tuning Fork Normal Force feedback
  • Geometrical friendly for online multiprobe all under active AFM feedback.
  • Low contact resistance and full insulation with glass upto the probe tip for high electro-potential resolution
  • Glass coating insulation can be overcoated with metal to emulate coax geometries for ultrahigh sensitivity electrical imaging
  • High cantilever design that minimizes cantilever electrical interference
