Physical and metering characteristics of three room temperature X-ray dosimeters used in clinical applications, PTW diamond, Thompson MOSFET and Scanditronix silicon diode are compared with polycrystalline diamond X-ray detectors. Development of dosimeters based on natural diamond carried out by PTW have provided superior characteristics with respect to other solid state silicon devices such diodes...
Microcrystalline and nanocrystalline diamond coatings grown by microwave plasma enhanced chemical vapor deposition (CVD) techniques are examined for their properties for applications as cold cathodes. Low-field electron field emission and high-yield secondary electron emission are promising properties of diamond and for applications to power modulators
Schottky diodes were fabricated using metal contacts to thin diamond films obtained by a plasma-enhanced chemical vapor deposition process. The diamond structure of the films was confirmed by X-ray diffraction patterns and Raman scattering spectra. Internal photoemission measurements were used to determine a barrier height of about 1.13 eV for both Au and Al contacts to p-type diamond films. Rectifying...
