  2. 1. Electrochemically etched pore arrays in silicon for X-ray imaging detectors

    University dissertation from Stockholm : KTH

    Author : Xavier Badel; Jan Linnros; Volker Lehmann; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik; TECHNOLOGY Electrical engineering; electronics and photonics Electrophysics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektrofysik;

    Abstract : Digital devices have now been introduced in many X-ray imaging applications, replacing slowly traditional photographic films. These devices are preferred as they offer real time imaging, easy handling and fast treatment of the images. READ MORE

  4. 2. Electronic materials growth and characterisation

    University dissertation from Stockholm : KTH

    Author : Michael A. Grishin; Ulf O. Karlsson; Massimo Sancrotti; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Photoemission; Ultra-short laser pulse; Thin film; Laser deposition; InSb; InAs; GaSb; Ferroelectrics; Elektrofysik; TECHNOLOGY Electrical engineering; electronics and photonics Electrophysics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektrofysik;

    Abstract : In this thesis the InSb(111), InAs(111) and GaSb(001) surfaces have been studied by means of time- and angle-resolved photoemission spectroscopy based upon the femtosecond laser system. The pump-and-probe technique allows to analyse both electron states in the valence band and normally unpopulated electron states above the valence band, which can be occupied by transiently excited carriers at the optically pumped surface.
