Novel Step Floating Islands VDMOS with Low Specific on-Resistance by TCAD Simulation

open access: yesMicromachines, 2022
A novel VDMOS with Step Floating Islands VDMOS (S-FLI VDMOS) is proposed for the first time in this letter, in order to optimize the breakdown voltage (BV) and the specific on-resistance (Ron,sp).

Evolution of the deformation profile of a horizontal thin ethanol layer when heated locally

open access: yesMATEC Web of Conferences, 2017
Thermocapillary breakdown of thin horizontal layer of ethanol when heated from a localized heat source was studied experimentally. The influence of layer depth on the breakdown process was investigated.

Reliability Prediction of Highly Scaled MOSFET Devices via Fractal Structure of Spatial Defects

open access: yesIEEE Access, 2019
The needs for continuous size reduction of metal-oxide-semiconductor field effect transistor (MOSFET) devices can cause serious reliability concerns. In particular, gate oxide breakdown is a key mechanism concerning the lifetimes of MOSFET devices.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

To infinity and some glimpses of beyond

open access: yesNature Communications, 2017
Certain physical problems such as the rupture of a thin sheet can be difficult to solve as computations breakdown at the point of rupture. Here the authors propose a regularization approach to overcome this breakdown which could help dealing with ...
