Abstract

We are going to investigate optical, transport and spin properties of semicondutor nanostructures and nanodevices. We intend to contribute to the understanding of physical properties for the point of view of both fundamental and applied physics for the development of novel semiconductor materials and devices. We propose to work on the following systems: Resonant Tunneling Diodes, InGaAsN/GaAs nanostructures and devices, GaBiAs layers and GaBoAs/GaAs nanostructures and magnetic oxides. (AU)
