We report the first monolithic vertical integration of a Si/SiGe HBT with a Si-based resonant interband tunnel diode (RITD) on a silicon substrate. This enables a 3-terminal negative differential resistance (NDR) device and the resulting devices have the distinguishing characteristics of adjustable peak-to-valley current ratio and adjustable peak current density (PCD) in the collector current under common emitter configuration at room temperature. We experimentally demonstrate its latching property and switching operation based on quantum mechanics.
