NDR characteristics of Si/SiGe RTD on Si

Negative differential resistance has been obtained from a number of devices from a Daimler Chrysler resonant tunnelling diode wafer at 77 K. A peak current density of 14.9 A/cm² with a peak-to-valley current ratio of 2.1 achieved.

Work is still progressing to try to improve on the performance of the RTDs.
