A Comprehensive Approach to Phonon Control for Enhanced Device Performance
Abstract
The goals of this program were to identify, develop and implement configurations in which phonons and the coupling of phonons to carriers lead to enhanced device performance. A significant component of our efforts centered on artificial semiconductor heterostructures such as quantum-wells, quantum-dots and superlattices. We considered existing devices such as quantum-heterostructure lasers and detectors and field-effect transistors as well as new concepts relying on the interaction between carriers and coherent phonons, specifically phonon-assisted lasing and tunneling. Highlights of this program include (i) the development of novel theoretical and experimental (ultrafast laser and x-ray) methods to generate and probe coherent high-frequency sound, optical phonons and polaritons, (ii) the improvement of phonon-based imaging techniques and development of new methods of phonon detection, (iii) the demonstration of high-performance quantum-dot lasers, and (iv) the optimization of and development of new epitaxial techniques for nitride growth.
