Abstract
A current-controlled resonant tunneling diode (RTD) having an InAs quantum well, AlGaSb barriers and InAs cladding layers is disclosed. The RTD of this invention displays an S-shaped negative differential resistance in its I-V relationship. As a result, the RTD displays the bistability necessary to greatly enhance the speed of operation of many key electronic components by eliminating the need for large load resistances in the circuit design.
