  2. 1. Numerical modelling of hot electron transport in Schottky-diodes and heterojunction structures

    Author : Hans Hjelmgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; n-GaAs; ; energy balance equations; dc-properties;

    Abstract : A one-dimensional drift-diffusion model, including energy balance equations, is used to model Schottky-diodes and heterojunction structures. The set of equations are solved simultaneously with a finite-difference iterative scheme. READ MORE

    Author : Xiangjun Shang; Ying Fu; Rajeev Ahuja; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Epitaxial InAs quantum dot solar cell;

    Abstract : This thesis studies p-i-n GaAs solar cells with self-assembled InAs quantum dots (QDs) inserted. The values of this work lie in three aspects. READ MORE

  5. 3. Design and Fabrication of III-V Semiconductor Devices for Millimetre- and Submillimetre Wave Applications

    Author : Svein M. Nilsen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Devices (various types of diodes) have been fabricated in several different III-V semiconductors (AlxGa1-xAs, In1-xGaxAs, and InAs). The III- V compound semiconductors lend themselves well to high frequency applications due to the high electron mobility that can be obtained. READ MORE

  6. 4. Electronic Structure Calculations: Materials with Weak and Strong Correlations

    Author : Krister Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoemission spectroscopy; band structure calculations;

    Abstract : This thesis is devoted to studies of various electronic properties which can be extracted from photoemission spectroscopy. Both weakly and strongly correlated systems are discussed, ranging from free electron metal surfaces to strongly correlated copper oxide compounds. READ MORE
