  2. 1. Electronic structure and optical properties of InGaAs and InAsP semiconductor quantum wires

    Author : Johan Hammersberg; Jörn M. Hvam; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In recent years intensive studies of semiconductor nanostructures or so-called semiconductor quantum structures have been performed in many research groups around the world. The research interest in quantum structures arises both from their potential to expose new physical phenomena in condensed matter physics, allied with fundamental quantum mechanical effects, and from their potential application in electronic and optoelectronic devices.

    Abstract : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.
