  1. 1. Optimizing sampling of important events in complex biomolecular systems

    Författare :Lindahl Viveca; Berk Hess; Erik Lindahl; Bert de Groot; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; free energy calculation; adaptive sampling; extended ensembles; membrane proteins; DNA; Biological Physics; Biologisk fysik;

    Sammanfattning : Proteins and DNA are large, complex molecules that carry out biological functions essential to all life. Their successful operation relies on adopting specific structures, stabilized by intra-molecular interactions between atoms. LÄS MER

  3. 2. Design and Construction of Low-Temperature Scanning Tunnelling Microscope for Spectroscopy

    Författare :Joakim Lindahl; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; thermophysical properties; stepper motor; ultra-high vacuum; inertial-mass; low temperatures; scanning tunneling microscopy; optical propertie; Fysik; Semiconductory physics; Physics; scanning tunneling luminescence; local probe; photon emission; local carrier injection; Halvledarfysik; Fysicumarkivet A:1998:Lindahl;

    Sammanfattning : This thesis discusses some of the fundamental requirements needed to be fulfilled when constructing a low temperature scanning tunnelling microscope (STM). Three different designs, two non-vacuum and one ultra-high vacuum (UHV), based on either inertial-mass or novel stepper motor principles are presented. LÄS MER
