  1. 1. Monte Carlo Studies of Charge Transport Below the Mobility Edge

    Författare :Mattias Jakobsson; Sven Stafström; Patrick Norman; Jérôme Cornil; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulation; charge transport; organic materials; conjugated polymers; DNA;

    Sammanfattning : Charge transport below the mobility edge, where the charge carriers are hopping between localized electronic states, is the dominant charge transport mechanism in a wide range of disordered materials. This type of incoherent charge transport is fundamentally different from the coherent charge transport in ordered crystalline materials. LÄS MER

  2. 2. Semi Markov chain Monte Carlo

    Författare :Håkan Ljung; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Mathematics; Adaptive simulation; error-in-the-variables; Kullback-Leibler divergence; Markov chain simulation; Markov chain Monte Carlo; semi-regenerative; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The first paper introduces a new simulation technique, called semi Markov chain Monte Carlo, suitable for estimating the expectation of a fixed function over a distribution π, Eπf(χ). Given a Markov chain with stationary distribution p, for example a Markov chain corresponding to a Markov chain Monte Carlo algorithm, an embedded Markov renewal process is used to divide the trajectory into different parts.

  3. 3. Monte Carlo Simulations of Homogeneous and Inhomogeneous Transport in Silicon Carbide

    Författare :Mats Hjelm; KTH; []
    Nyckelord :simulation; Monte Carlo; SiC; charge transport; MOSFET; MESFET;

    Sammanfattning : The importance of simulation is increasing in the researchon semiconductor devices and materials. Simulations are used toexplore the characteristics of novel devices as well asproperties of the semiconductor materials that are underinvestigation, i.e. generally materials where the knowledge isinsufficient.

  4. 4. Monte Carlo and Charge Transport Simulation of Pixel Detector Systems

    Författare :David Krapohl; Göran Thungström; Christer Fröjdh; Cinzia da Via; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo Simulation; TCAD; pixel detectors; Medipix; Timepix; Finite Element Simulation;

    Sammanfattning : This thesis is about simulation of semiconductor X-ray and particledetectors. The simulation of a novel coating for solid state neutrondetectors is discussed as well as the implementation of a simulationframework for hybrid pixel detectors. LÄS MER

  5. 5. On Monte Carlo simulation and analysis of electricity markets

    Författare :Mikael Amelin; Lennart Söder; Hans Ravy; KTH; []
    Nyckelord :Electrical engineering; electricity markets; power systems; monte carlo simulation; Elektroteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This dissertation is about how Monte Carlo simulation can be used to analyse electricity markets. There are a wide range of applications for simulation; for example, players in the electricity market can use simulation to decide whether or not an investment can be expected to be profitable, and authorities can by means of simulation find out which consequences a certain market design can be expected to have on electricity prices, environmental impact, etc. LÄS MER
