  5. 4. Fabrication and Characterization of Aluminum Single Electron Transistors for Scanning Probes

    Författare :Henrik Brenning; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radio frequency single electron transistor; scanning probe; charging energy; nano fabrication; noise; scanning SET; SET; cantilever; AFM; RC-product; micro mechanics;

    Sammanfattning : The main objective of the work presented in this thesis was to fabricatescanning single electron transistor probes that operate at pumped liquid heliumtemperatures. This required single electron transistors (SETs) with low resistance (R_) and relatively high charging energy (E_C), and the technology tointegrate SETs onto probes. LÄS MER

  7. 5. Modeling of non-equilibrium scanning probe microscopy

    Författare :Alexander Gustafsson; Magnus Paulsson; Tchavdar Todorov; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; scanning tunneling microscopy; molecular dynamics; density functional theory; non-equilibrium Green s functions; Condensed Matter Physics; Kondenserade materians fysik;

    Sammanfattning : The work in this thesis is basically divided into two related but separate investigations.The first part treats simple chemical reactions of adsorbate molecules on metallic surfaces, induced by means of a scanning tunneling probe (STM). The investigation serves as a parameter free extension to existing theories. LÄS MER
