  1. 21. Interface Roughness in Quantum Cascade Lasers

    University essay from Lunds universitet/Matematisk fysik

    Author : Kasparas Antanas Krivas; [2015]
    Keywords : Quantum Cascade Lasers; Interface Roughness; Modeling; Physics and Astronomy;

    Abstract : The quantum cascade laser (QCL) is a solid state device capable of generating the coherent mid-infrared and terahertz radiation. It is made from layers of different semiconducting materials. This layered structure gives rise to sub-bands, that are employed to achieve charge inversion necessary for lasing. READ MORE

  3. 22. A first-principles non-equilibrium molecular dynamicsstudy of oxygen diffusion in Sm-doped ceria

    University essay from Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska fakulteten

    Author : Johan Klarbring; [2015]
    Keywords : density functional theory; non-equilibrium molecular dynamics; color diffusion; Sm-doped ceria; CeO2; ionic conductivity; solid oxide fuel cells;

    Abstract : Solid oxide fuel cells are considered as one of the main alternatives for future sources of clean energy. To further improve their performance, theoretical methods able to describe the diffusion process in candidate electrolyte materials at finite temperatures are needed. READ MORE

  4. 23. Non-equilibrium dynamics ofa single spin in a tunnel junction

    University essay from Materialteori

    Author : Henning Hammar; [2014]
    Keywords : molecular electronics; spintronics; solid state theory; spin system; quantum computers;

    Abstract : Making spintronic devices is a hot topic for future technical development. In this work the non-equilibrium dynamics of a single spin in a tunnel junction is analyzed and numerically simulated. This is done in order to understand the dynamics of e.g. READ MORE

  5. 24. Parameter Estimation of a non-Equilibrium Asset Pricing Model and Performance Analysis of the Calibration in Terms of Sloppiness

    University essay from KTH/Matematisk statistik

    Author : Andreas Lagerqvist; [2014]
    Keywords : ;

    Abstract : Prices of assets traded in stock markets often exhibit out of equilibrium behaviours, e.g. bubbles and recessions. Yukalov et al. READ MORE

  6. 25. Wavefunction and spectral properties of single-particle emitters

    University essay from Lunds universitet/Fysiska institutionen

    Author : Elina Locane; [2013]
    Keywords : Physics and Astronomy;

    Abstract : The past six years have seen the development of fast and accurate single-particle sources, with possible applications in metrology, nanoelectronics, quantum information processing, and single-electron quantum optics. These mesoscopic devices also enable us to gain more insight into the quantum mechanics of interacting fermions. READ MORE
