    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Growth dynamics; Monte Carlo; semiconductor quantum dot; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Semiconductors and related low-dimensional nanostructures are extremely important in the modern world. They have been extensively studied and applied in industry/military areas such as ultraviolet optoelectronics, light emitting diodes, quantum-dot photodetectors and lasers. READ MORE

  5. 3. Controlled growth of hexagonal GaN pyramids and InGaN QDs

    Author : Anders Lundskog; Erik Janzén; Urban Forsberg; Per-Olof Holtz; Lars-Erik Wernersson; Linköpings universitet; []
    Keywords : ;

    Abstract : Gallium-nitride (GaN) and its related alloys are direct band gap semiconductors, with a wide variety of applications. The white light emitting diode (LED) is of particular importance as it is expected to replace energy inefficient light bulb and hazardous incandescent lamps used today. READ MORE
