Abstract
A resonant tunneling diode (400) made of a quantum well (406) with tunneling barriers (404, 408) made of two different materials such as calcium fluoride (408) and silicon dioxide (404). The calcium fluoride provides lattice match between the emitter (410) and the quantum well (406). Further resonant tunneling diodes with silicon lattice match barriers may be made of III-V compounds containing nitrogen.
