Abstract :
Extends into the high field regime the usual (very low field) treatment of the one-dimensional (1D) ballistic resistor that leads to quantised resistance. The authors find nonlinear resistance and eventually negative differential resistance (NDR) with a high-frequency cutoff above 10 THz. They outline preliminary experimental evidence in support.
