Microelectronic magnetic sensors are essential in diverse applications, including automotive, industrial, and consumer electronics. Hall-effect devices hold the largest share of the magnetic sensor market, and they are particularly valued for their reliability, low cost and CMOS

We present iron-doped beta gallium oxide (Fe-ßGa2O3) as a candidate for photoconductive semiconductor switches (PCSSs) with sub-bandgap light. From a commercially available Fe-ßGa2O3 wafer, we first did material characterization. This included measurements of absorption coefficie

This paper reports on the creation of a novel 3D Hall-effect sensor based on an anisotropically etched, inverted pyramid structure. Specific biasing and sensing contact configurations are employed to extract the in-plane or out-of-plane components of the magnetic field, eliminati

In this work, we demonstrate and model the deep-level defect physics of semi-insulating gallium arsenide bulk photoconductive semiconductor switches (PCSS) with gap size of 10 μ and 25 μ in dark-mode operation. Experimental measurements up to biasing field of 10 kV/cm show near-b

This article provides an overview of power semiconductor devices (PSDs) for the distributed energy resource (DER) system. To begin with, an overview of electrically triggered silicon carbide (SiC) and gallium nitride (GaN) devices followed by a brief narration of ultrawide bandga
