The ability to minimise, control and manipulate defects in CVD diamond has grown rapidly over the last ten years. The application which best illustrates this is probably that of quantum information processing (QIP) or ‘diamond spintronics’. QIP i

In this paper, we review the suitability of diamond as a semiconductor material for high-performance electronic applications. The current status of the manufacture of synthetic diamond is reviewed and assessed. In particular, we consider the quality

We characterized high-quality polycrystalline diamond with large grains and fabricated polycrystalline diamond field effect transistors (FETs). The polycrystalline diamond had (110) preferred orientation, and its typical grain size was ∼ 100 μm. W

Diamond is potentially a very suitable material for use as a radiation dosimeter; the wide band gap results in low dark currents and low sensitivity to visible light, the high carrier mobilities can give rapid response, the very high density of stron

Natural diamond has been investigated as a radiotherapy dosimeter with good results. However, the lack of readily available ‘detector grade’ natural diamonds make their application in this area difficult. Advances in the production of diamond by

Defects in free-standing diamond films grown by microwave-plasma-assisted chemical vapour deposition have been studied by electron paramagnetic resonance (EPR). The EPR spectra observed for the as-grown material each consisted of two distinguishable

Laser-induced damage threshold (LIDT) measurements have been made on bulk polycrystalline (BP) CVD diamond plates using 0.532, 1.06 and 10.6 μm radiation and compared with measurements on natural type IIa diamond samples. Using 10.6 μm radiation, d
