Abstract
Velocity-electric field characteristics and evidence for travelling high field domains are reported for hot-electron conduction in single crystal epitaxial films of n-PbTe. Measurements were performed at 77 K, using nanosecond pulse techniques. Contact effects cause differences in the shape of the velocity-field curve and also possibly in the nature of high-field current instabilities. Pulsed Hall measurements reveal substantial time-dependent carrier generation and may indicate the presence of high-field domains.
