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.

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

   Författare :Saman Majdi; Jan Isberg; Ricardo S. Sussmann; Uppsala universitet; []
   Nyckelord :Single crystal diamond; carrier transport; CVD diamond; time-of-flight; mobility; IR detector; compensation; diamond diode; drift velocity; thermal detector;

   Sammanfattning : Diamond is a promising material for high-power, high-frequency and high- temperature electronics applications, where its outstanding physical properties can be fully exploited. It exhibits an extremely high bandgap, very high carrier mobilities, high breakdown field strength, and the highest thermal conductivity of any wide bandgap material. LÄS MER

5. 4. Development of tissue-equivalent CVD-diamond radiation detectors with small interface effects

   Författare :Bartosz Górka; Bo Nilsson; José M. Fernández-Varea; Anders Brahme; Hugo Palmans; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD-diamond detector; tissue-equivalent encapsulation; dosimetry; Monte Carlo simulation; Physics; Fysik; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : Due to its close tissue-equivalence, high radiation sensitivity, dose and dose-rate linearity, diamond is a very promising detector for radiation therapy applications. The present thesis focuses on the development of a chemical vapour deposited (CVD) diamond detector with special attention on the arrangement of the electrodes and encapsulation having minimal influence on the measured signal.

7. 5. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization

   Författare :Vaiva Kaveckyte; Åsa Carlsson Tedgren; Alexandr Malusek; Hamza Benmakhlouf; Jan Seuntjens; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dosimetry; brachytherapy; solid-state detectors; Monte Carlo;

   Sammanfattning : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). LÄS MER
