Design Comparison of SiC MOSFETs for Linear-Mode Operation


Source: US Army Research Lab Authors: Heather O'Brien, Damian Urciuoli, Aderinto Ogunniyi, Brett Hull August 2019 "Abstract: Silicon carbide metal-oxide semiconductor field-effect transistors (MOSFETs) were designed and fabricated for linear-mode applications. The MOSFETs have a chip area of 3.3 ? 3.3 mm and a voltage-blocking rating up to 1200 V. The device design parameters, such as chan... » read more

Fiber-imprint patterning The École polytechnique fédérale de Lausanne (EPFL)--a research institute/university in Lausanne, Switzerland--has put a new twist in nano-imprint patterning technology. It has devised a way to imprint tiny or nano-metric patterns on hollow polymer fiber. Using a technique called thermal drawing, tiny patterns can be printed on both the inside and the outside of ... » read more
