Hi, I am planning to figure out the I-V charateristics curve for a silicon wafer under watlab AFM ( The Dimension 3100 in WATLABS has our TUNA module so, yes it will do I-V measurements ), UW. We made our sample as conductive as I could. I coated ~15 nm Cr on top and Au (~10nm) beneath the Silicon piece and then attached the sample to the chuck with
