  1. 1. Scanning Probe Microscopy: Design and Applications

    Author : Håkan Olin; [1993]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A compact scanning tunneling microscope (STM) and a scanning ion-conductance microscope (SICM) has been constructed. The concentric microscope head was built around a commercial piezoelectric inchworm motor that was used for coarse positioning. The microscope has a high resonance frequency (9.6 kHz), low noise (0.

  3. 3. Design and Applications of Sub-Kelvin Tunnelling Microscopy

    University dissertation from Tryckeriet i E-huset, Lunds universitet

    Author : Per Anders Davidsson; [1995]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The main part of the work presented in this thesis deals with the extension of tunnelling microscopy to the temperature interval below one kelvin. Several microscopes have been designed and manufactured, one for ultra high vacuum at room temperature and two for sub-kelvin cooling. READ MORE

  4. 4. Scanning probe techniques as an investigation tool for semiconductor nanostructures and devices

    University dissertation from Lund University (Media-Tryck)

    Author : Jovana Colvin; [2019-10-15]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductors; AFM; STM; KPM; SCM; c-AFM; Crystal growth; Doping; Defects;

    Abstract : Semiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage. This includes harvesting of energy (solar cells) and saving of energy, e.g. in lighting (light-emitting diodes, LEDs) and transfer of energy (power devices). READ MORE

  5. 5. DFT calculations of initial localized corrosion of aluminum Influence of aqueous ad-layer, chloride ions, and intermetallic particles

    University dissertation from KTH Royal Institute of Technology

    Author : Min Liu; Jinshan Pan; Ying Chen; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aluminum alloys; alumina; chloride; surface adsorption; aqueous ad-layer; localized corrosion; corrosion initiation; work function; micro-galvanic effect; density-functional theory; Volta potential; scanning kelvin probe force microscopy; Kemi; Chemistry;

    Abstract : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. READ MORE
