IV measurement between the top Ti/Ni/Ag contacts is performed. Nonlinear IV curve happens for large current/voltage range. For lower IV range, the IV curve between two contacts is linear. However, the voltage between the other contact pair is always nonlinear.
20120725 Au2b IV topcontact.xlsx - 7/31/2012 Analysis on IV data between the top contacts. The Au:Si layer seems to be very resistive, causing a significant portion of the current to flow through the diode and the substrate instead of flowing through the hyperdoped region.
