Measurement setup
- General
- t = -20șC*
- IV
- from 0 to -1000V to BACK, PAD and INNERMOST GR at GND
- CV
- same setup as IV plus:
- dV = 0.5 V
- nu = 1000 Hz
Nota Bene
- In CV measurements the GR is really at GND while the PAD is at R x I_leak, where R = 40 kOhm
Analysis guide
- No depletion up to 1000V for flunce larger than 1e15
- Two different slopes in CV plots for fluence greater than 1e15; other levels

Data
- IV
- The first column is bias, the second is total current, the third is PAD current
- CV
- The first column is the real voltage difference between BACK and PAD; 4th column is the bias set on the Keithley; 2nd column is capacitance; 3rd Conductivity; last column is total current
