2. 1. Electronic Properties of Diamond

   Author : Markus Gabrysch; Jan Isberg; Mats Leijon; Johan Hammersberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; CVD diamond; wide-bandgap semiconductor; time-of-flight; pair-creation energy; electronic devices; detector; Elektronik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

   Abstract : 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 compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

   Abstract : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.

6. 4. Electronic Properties of Nanotubes

   Author : Alex Kleiner; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis deals with various aspects of the electronic properties of carbon nanotubes and of generic nanotubes in magnetic fields. Carbon nanotubes are highly symmetric objects on the nanometer scale which show an interesting interplay of their geometry with electronic properties. READ MORE

7. 5. Surface analysis of low dimensional materials : revealing their electronic properties by advanced spectroscopy

   Author : Vladimir Miranda la Hera; Thomas Wågberg; Eduardo Gracia-Espino; Tomas Edvinsson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-dimensional materials; surface science; surface-sensitive techniques; angle-resolved photoemission spectroscopy; ultraviolet photoemission spectroscopy; electronic properties;

   Abstract : Low-dimensional materials (0D, 1D, 2D) have been widely used to develop modern miniaturized (micro- and nano-) technology. The use of these materials come from their extraordinary optical, electrical, thermal, and mechanical properties, which are very different from the bulk crystal. READ MORE
