2. 1. Electrical and Optical Properties of AlGaAs/GaAs Aperiodic Superlattices and Resonant Tunneling Diodes. Theory, Design and Applications

   Author : Simon Mang Cao; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; exciton-assisted transport; miniband; high-speed quantum electronics; optical properties; ultrafast optoelectronics; field-induced transport; irregular superlattices; nanometer-scale heterostructures; laser diodes; resonant tunneling;

   Abstract : The objective of the work presented in this thesis is to study quantum transport and optical properties of aperiodic superlattices and resonant tunneling diodes using III-V semiconductor heterostructures grown by molecular beam epitaxy. The study follows a procedure of theoretical modeling, computer-aided design and simulation, sample growth, and measurements. READ MORE

4. 2. Electronic Structure and Transport in Nanofabricated Low-Dimensional Semiconductor Systems : A theoretical study

   Author : Chuan-Kui Wang; Hongqi Xu; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Systematic studies of the transport properties in one type of low-dimensional semiconductor nanostructures, in which the motion of carriers is governed by quantum mechanics, are presented in this thesis. In addition, the electronic states in lowdimensional systems fabricated from GaAs / Al?Ga1-?As heterostructures have been investigated by using both transport methods and the static calculations.
