Space Charge Modulated Electrical Breakdown [PDF]
Scientific Reports, 2016 AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...

Electrical breakdown in tissue electroporation [PDF]
Biochemical and Biophysical Research Communications, 2015 Electroporation, the permeabilization of the cell membrane by brief, high electric fields, has become an important technology in medicine for diverse application ranging from gene transfection to tissue ablation. There is ample anecdotal evidence that the clinical application of electroporation is often associated with loud sounds and extremely high ...

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 ...

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 ...
