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

open access: yes, 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 ...
