The SiC vacuum field-effect transistor (VacFET) was first reported in 2010 as a diagnostic tool for characterizing the fundamental properties of the inverted SiC semiconductor surface without confounding issues associated with thermal oxidation. In t

This is the first high-temperature static and dynamic characterization of a half-bridge power module using 1200 V, 45 mΩ depletion-mode vertical JFETs. With only 36 mm2 of JFET area, the peak pulsed current is measured to be nearly 500 A at room tem

We introduce the vacuum field-effect transistor (VacFET), the first SiC FET to use a vacuum-sealed cavity in place of the traditional, solid gate dielectric. This device architecture eliminates the need to thermally oxidize the SiC surface, a practic

The high-temperature static and dynamic characteristics of the new 1200 V, 45 mΩ, 9 mm2 depletion-mode SiC vertical trench junction field-effect transistor (vtJFET) are compared with those of a 1200 V, 50 mΩ, 9 mm2 enhancement-mode SiC vtJFET. It i

This article presents cross-sectional transmission electron microscopy and molten-potassium hydroxide etching studies of (111) 3C-SiC diodes which we previously reported to be free of forward-voltage drift despite abundant electroluminescent linear f

pn diodes have recently been fabricated from 3C-SiC material heteroepitaxially grown atop on-axis 4H-SiC mesa substrate arrays [1,2]. Using an optical emission microscope (OEM), we have investigated these diodes under forward bias, particularly inclu

p-n diodes were fabricated from 3C-SiC films heteroepitaxially grown atop on-axis, Si-face (0001) 4H-SiC mesa substrate arrays [P. G. Neudeck et al., Mater. Sci. Forum 433-436, 213 (2003); 527-529, 1335 (2006)]. Images taken by electroluminescence-ba

Since the release of power SiC JFETs in 2008 and power SiC MOSFETs in 2011, there are now more choices of SiC power transistors than ever before available to industrial power electronics markets. To inform prospective users, this paper surveys critic

The fast switching speeds, large current handling capability and superior thermal properties of SiC makes SiC Vertical Trench JFETs (VJFETs) ideal candidates for power electronic applications. This paper reports on the recent progress in the developm
