Abstract
The authors provide evidence for both voltage- and current-controlled negative differential resistance instabilities in the one-dimensional ballistic resistor driven into the hot-electron regime. Quantum reflections are used to explain the former effect, while extra electron subbands provide the current 'filaments' in the latter case.Keywords
