    Abstract : The topic of III-V nanowires is still, after more than two decades, a growing and lively research area. The areas of application are wide and contain such important topics as energy harvesting, cheap and efficient lighting, high efficiency detectors and new types of electronics. III-V materials offer properties superior to the widely used Si. READ MORE

  5. 23. Experimental and Theoretical Studies of Metal Adsorbates Interacting with Elemental Semiconductor Surfaces

    Author : Hafiz Muhammad Sohail; Roger Uhrberg; Leif Johansson; Kevin E. Smith; Linköpings universitet; []
    Keywords : ;

    Abstract : Metal adsorbates on semiconductor surfaces have been widely studied over the last few decades. The main interest is focused on various one or two-dimensional structures that exhibit interesting electronic and atomic properties. This thesis focuses on metal adsorbates interacting with the Si(111) and Ge(111) surfaces. READ MORE
