  1. 6. InAs and high-k oxides, a scanning tunnelling study of their interfaces

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Mattias Åstrand; [2018]
    Keywords : Semiconductor; High-k; Atomic layer deposition; Scanning tunnelling microscopy; Scanning tunnelling spectroscopy; Physics and Astronomy;

    Abstract : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. READ MORE

  3. 7. Leakage current and breakdown of HfO2/InGaAs MOS capacitors

    University essay from Lunds universitet/Fysiska institutionen

    Author : Edvin Winqvist; [2015]
    Keywords : breakdown; leakage; ingaas; hfo2; Physics and Astronomy;

    Abstract : With the constant downscaling of transistors, silicon as a production material is falling out of favour because of increasing power consumption when the size of devices becomes smaller. Compound materials from group III-V in the table of elements are promising candidates to replace silicon. READ MORE

  4. 8. Thermal Stability of cubic and nanocrystalline arcevaporated TiCrAlN coatings

    University essay from Linköpings universitet/Nanostrukturerade material; Linköpings universitet/Tekniska högskolan

    Author : Hassan Saleem; [2014]
    Keywords : ;

    Abstract : (TixCryAlz)N coatings were deposited on WC-Co substrate using cathodic arc evaporation technique to investigate phase transformation, thermal stability, and high temperature mechanical properties. Two compositions Ti0.34Cr0.33Al0. READ MORE

  5. 9. Atomic scale modication of semiconductor nanostructure surfaces

    University essay from Lunds universitet/Fysiska institutionen

    Author : Robin Sutinen Svärd; [2013]
    Keywords : STM; GaSb; InAs; Surface science; XPS; Physics and Astronomy;

    Abstract : The III-V semiconducting compounds InAs and GaSb were studied using scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). Different crystal planes of each material were investigated separately, including wafers of InAs(111)A, InAs(111)B, InAs(110), GaSb(100), GaSb(110) as well as nanowires consisting of InAs. READ MORE

  6. 10. Surface Passivation of CIGS Solar Cells by Atomic Layer Deposition

    University essay from KTH/Kraft- och värmeteknologi

    Author : Sara Motahari; [2013]
    Keywords : solar cells; CIGS; thin film; surface passivation; atomic layer deposition;

    Abstract : Thin film solar cells, such as Cu(In,Ga)Se2, have a large potential for cost reductions, due to their reduced material consumption. However, the lack in commercial success of thin film solar cells can be explained by lower efficiency compared to wafer-based solar cells. READ MORE
