As commonly reported in other power devices, the lateral deep-depletion diamond MOSFET (D3MOSFET) suffers from an electric crowding effect at gate-edge toward drain. This behavior leads to a premature breakdown of gate-oxide (made Al2O3) below expected performances material. The current article focuses on design field-plated D3MOSFET order improve device voltage up 1 kV. Based 2D TCAD simulatio...

Abstract. A new approach of the Polarity Effect in connection to the Corona Current and the Ground Effect in small rod-plate and rod-rod air gaps is presented. The influence of the polarity of the applied voltage to the corona onset voltage or the breakdown voltage of small rod-plate and rod-rod air gaps is investigated. The influence of the grounding of one of the electrodes, to the field dist...

The breakdown strength characteristic of Low Density Polyethylene films (LDPE) under DC voltage application and the effect of water absorption have been studied. Mainly, our experiment was investigated under two conditions; dry and heavy water absorption. Under DC ramp voltage, the result found that the breakdown strength under heavy water absorption has a lower value than dry condition. In ord...

We present an experimental study of the DC breakdown voltage of MEMS interdigitated aluminum electrodes with gaps ranging from 10 to 500 μm. Unlike most research on MEMS electrodes that was done at atmospheric pressure, our work has focused on the effect of gas pressure and gas type on the breakdown voltage. A main goal was to identify geometries that favor the creation of low-voltage discharge...
