- 6/13/2012 Spin photoresist and bake at 115 C for 1 minute to protect sample from debris during laser cut
- 6/16/2012 Remove resist
- 7/26/2012 IV on diode, taken with Keithley 4200 after instrument autocalibration. Good rectifying behavior is observed only for diode sample 2b (n-Si, (100)). Diode sample 3a (p-type, (111)) does not rectify.
