Indirectly Measured Ambient Electric Fields for Lightning Initiation in Fast Breakdown Regions
Geophysical Research Letters, 2020 We report a new approach to measure indirectly the ambient thunderstorm electric fields in fast positive breakdown regions. For a given geometry of the discharged fast breakdown region, we show that there is a minimum ambient electric field required to ...

Effect of Acceptor Traps in GaN Buffer Layer on Breakdown Performance of AlGaN/GaN HEMTs
Micromachines, 2022 In this paper, Silvaco TCAD software is used to simulate the buffer traps in AlGaN/GaN high electron mobility transistors (HEMTs), and its effects on the breakdown performance and key parameters of the devices are investigated by changing the position ...

A model study of corona emission from hydrometeors [PDF]
, 1998 The maximum measured electric fields in thunderclouds are an order of magnitude less than the fields required for electric breakdown of the air. One explanation for lightning initiation in these low fields is that electric breakdown first occurs at the ...

The inception of pulsed discharges in air: simulations in background fields above and below breakdown [PDF]
, 2014 We investigate discharge inception in air, in uniform background electric fields above and below the breakdown threshold. We perform 3D particle simulations that include a natural level of background ionization in the form of positive and O$_{2}^-$ ions.

GaN/Si Heterojunction VDMOS with High Breakdown Voltage and Low Specific On-Resistance
Micromachines, 2023 A novel VDMOS with the GaN/Si heterojunction (GaN/Si VDMOS) is proposed in this letter to optimize the breakdown voltage (BV) and the specific on-resistance (Ron,sp) by Breakdown Point Transfer (BPT), which transfers the breakdown point from the high ...

Parallel electric fields produced by ionospheric injection [PDF]
Annales Geophysicae, 2023 It is well known that there exists a thin layer in the lower boundary of the ionosphere between altitudes of 80 and 140 km in which collisional ions and collisionless electrons mix.
