    Sammanfattning : High-temperature electronics find use in extreme environments, like data logging in downhole drilling for geothermal energy production, inside of high-temperature turbines, industrial gas sensors and space electronics. The simplest systems use a sensor and a transmitter, but more advance electronic systems would additionally require a microcontroller with memory. LÄS MER

    Sammanfattning : In this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy.
