TITLE: "Quantum Effects in Resonant Tunneling Structures"

SPEAKER: Professor Theda Daniels-Race,

A discussion of the effects of molecular beam epitaxy (MBE) parameters and sample design configuration for asymmetric double barrier resonant tunneling structures (ADBRTs) is presented. Sample sets were grown using a Riber 32 R&D system with custom designed software for temperature monitoring and shutter control. Room temperature and 77 K current-voltage measurments were made in conjunction with low temperature photoluminescence spectra. This talk will briefly describe the phenomenon of resonant tunneling, the extrapolation of phonon characteristics via the asymmetric barrier configuration, and the electrical/optical results obtained.
