  1. 1. Charge Transport in Single-crystalline CVD Diamond

    Författare :Markus Gabrysch; Jan Isberg; Mats Leijon; Milos Nesladek; Uppsala universitet; []
    Nyckelord :CVD diamond; wide-bandgap semiconductor; single-crystalline diamond; carrier transport; time-of-flight; drift velocity; mobility; compensation; pair-creation; electronic devices; diamond detector; diamond diode;

    Sammanfattning : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties, as compared to other (wide bandgap) semiconductors, make it desirable to develop single-crystalline epitaxial diamond films for electronic device and detector applications.

  2. 2. Microengineered CVD Diamond Surfaces : Tribology and Applications

    Författare :Joakim Andersson; Staffan Jacobson; Arto Alahelisten; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Diamond; DLC; Tribology; Friction; Environment; Microengineering; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Recent developments in thin film synthesis of diamond have facilitated a host of new technical applications. These are motivated by the many attractive properties of diamond, for example high hardness, chemical inertness, transparency and heat conductivity. Unfortunately, these properties also make it difficult to fashion complex geometries. LÄS MER

  3. 3. Experimental Studies of Charge Transport in Single Crystal Diamond Devices
