Inadequacy of the Mott-Schottky equation in strongly pinned double Schottky barriers with no deep donors [PDF]

, 2012
The capacitive behaviour of an intergranular double Schottky barrier in a polycrystalline semiconductor was evaluated. We found that the widely applied version of the Mott-Schottky equation can lead to significant errors.

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 ...
