  1. 6. 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

  2. 7. 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

  3. 8. Advanced Metal Oxide Semiconductors for Solar Energy Harvesting and Solar Fuel Production

    Author : Pedram Ghamgosar; Alberto Vomiero; Nils Almqvist; Omer Nour; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photovoltaic; Semiconductors; Photoelectrochemical cell; Solar fuel; Water splitting; Hydrogen evolution; Oxygen evolution; Experimentell fysik; Experimental Physics;

    Abstract : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source which is able to cover the terms sustainability is considered as a favorable alternative. READ MORE
