Materials Characterization

Atomic Force Microscopy (AFM)

CNSI has a room devoted to AFM including 2 models Asylum and NanoScope. Contact Mark Cornish <cornish@engineering.ucsb.edu> to get tips and register. The cleanroom also has a NanoScope AFM.

Asylum AFM

NanoScope AFM

= Optical Characterization

LI curves

"Example:" This technique allows you to measure output power vs. injection current. The follwoing equipment is used:

  • Keithley (link to equipment)
  • Agilent powermeter (link)

The measurement can be controlled using this (link) software. A sample plot looks like this: (insert picture). More about this technique can be found in:
