Modified Mott-Schottky Analysis of Nanocrystal Solar Cells

, 2011
Mott-Schottky analysis is adapted to determine the built-in bias (Vbi) and doping density (N) of lead sulfide-zinc oxide colloidal quantum dot heterojunction solar cells. We show that charge injection barriers at the solar cell's electrodes create a constant capacitance that distorts the junction's depletion capacitance and result in erroneous Vbi and ...

Observation of negative differential conductance in a reverse-biased Ni/Ge Schottky diode

, 2009
We report the experimental observation of negative differential conductance in a Ni/Ge Schottky diode. With the aid of theoretical models and numerical simulation we show that, at reverse bias, electons tunnel into the high electric field of the ...
