The use of CVD diamond for high-power switching using electron beam exitation

Multiple growth and characterization of thick diamond single crystals using chemical vapour deposition working in pulsed mode

“…During the last decade, many progresses were achieved in diamond growth by micro-wave plasma assisted chemical vapour deposition (MPCVD) leading to the production of device-grade single crystal diamond [1][2][3][4]. However, to sustain the very high voltages involved in high power devices, the use of a transverse or volume configuration is often necessary, such as for example for photoswitches [5]. As a consequence, hundreds of microns of extremely high quality diamond crystals have to be synthesized.…”

The control of growth parameters in the synthesis of high-quality single crystalline diamond by CVD

“…The progress that has been achieved over the past few years on the growth of thick and high-purity homoepitaxial single-crystal diamond by chemical vapour deposition (CVD) has open a range of possible applications in areas such as optics or power electronics [1][2][3][4]. The synthesis of single-crystal diamond layers by CVD exhibiting very high values of electron and hole mobilities and very long free-carrier recombination lifetimes has been recently reported [5].…”

High quality MPACVD diamond single crystal growth: high microwave power density regime

“…These are made up of a MIM-type structure (metal-insulator-metal), i.e. an intrinsic diamond film a few hundred micrometres thick sandwiched between two ohmic contacts [7]. Besides the difficulty in achieving such contacts, this application also requires very high material quality and the films must also be several hundred micrometres thick.…”
