  4. 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.

  5. 4. Monte Carlo simulation of electron transport in semiconducting zigzag carbon nanotubes

    Författare :Kannan Thiagarajan; Ulf Lindefelt; Hans-Erik Nilsson; Michele Goano; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotubes; Monte Carlo method; drift velocity; mobility; electron-phonon scattering; and electron-defect scattering.;

    Sammanfattning : Since the advent of nanoscale material based electronic devices, there has been a considerable interest in exploring carbon nanotubes from fundamental science and technological perspectives. In carbon nanotubes, the atoms form a cylindrical structure with a diameter of the order 1nm. LÄS MER

  7. 5. Thermodynamics of Protein Folding and Design

    Författare :Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

    Sammanfattning : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. LÄS MER
