One-dimensional ballistic resistor in hot-electron regime: nonlinear and negative differential resistance to 10 THz

Abstract

We extend into the high field regime the usual (very low field) treatment of the one-dimensional (ID) ballistic resistor that leads to quantised resistance. We find nonlinear resistance and eventually negative differential resistance (NDR) with a high-frequency cutoff above 10 THz. We outline preliminary experimental evidence in support.
