High Energy Electron Injection into Semiconductor Superlattices, Quantum Wells, and Quantum Wires.

摘要

The goal of this contract has been to investigate high energy injection of carriers into semiconductor multiple quantum well structures, superlattices, and quantum waveguide structures. Towards this goal, significant accomplishments have been obtained by the PI through a broad range of ongoing research efforts. To briefly summarize the accomplishments under this contract, focus will be given to four different research fronts to which the resources of the grant were expended: (1) Carrier relaxation during ultra-fast laser excitation in multiple quantum well structures, (2) Fabrication and characterization of resonant tunneling diodes, (3) Modeling and fabrication of quantum waveguide structures, and (4) Modeling and fabrication of a Superlattice Base Transistor.
