Abstract

This proposal foresees the search and development of nanoscale electro-optical semiconductor devices and the systematic study of their optical and transport properties. The goals set now are framed within the scope of a collaborative work between the experimental growth, electro- optical spectroscopy, and theoretical calculations. Previous projects allowed the evolution of our research from topics of fundamental condensed matter physics towards applications where the specialization in manufacturing and modeling of low-dimensional structures and devices appear in communion, combining the theoretical and experimental expertise of the project partners. The theoretical and experimental efforts include the study of transport and electro-optical phenomena in resonant tunneling devices (RTD) applied as photodetectors, accurate sensors, and LEDs, as well as low-dimensional wave guides integrated with quantum dots (QD) as devices for transmission and storage of information. In topics of fundamental semiconductor physics we propose to further deepen the research and simulation of semiconductor QDs, quantum rings, and mono-layers affected by impurities and structural defects. This path has already open new research horizons by combining affective mass models and ab-initio calculations. Many of the problems tackled are grounded on experimental challenging questions where preliminary results show interesting effects of confinement and topology of the strain fields inherent to the growth of these structures. The envisioned technological applications allow betting on the potential of this project for the generation of patents. (AU)
