3D Hall-Effect Magnetometer Using a Single Inverted Pyramid Structure

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, eliminating cross-sensitivity by symmetry. Simulations were performed to...

Overview of Wide/Ultra-Wide Bandgap Power Semiconductor Devices for Distributed Energy Resources

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 bandgap (UWBG) PSDs and, subsequently, an overview of optically...

Observation and Modeling of Near-Bistable Dark-Mode Current-Voltage Characteristics in Semi-Insulating Gallium Arsenide with Implications for Photoconductors

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-bistable characteristics in the dark-mode current-voltage...

Synergistic toughening and electrical functionalization of an epoxy using MWCNTs and silane- /plasma-activated basalt fibers

This work studied the effects of adding short basalt fibers (BFs) and multi-walled carbon nanotubes (MWCNTs), both separately and in combination, on the mechanical properties, fracture toughness, and electrical conductivity of an epoxy polymer. The surfaces of the short BFs were either treated using a silane coupling agent or further...

Adhesion Improvement of Thermoplastics-Based Composites by Atmospheric Plasma and UV Treatments

The present work is concerned with adhesive bonding of thermoplastic composites used in general aerospace applications, including polyphenylene sulfide (PPS), polyetherimide (PEI) and polyetheretherketone (PEEK) carbon fibre composites. Three different surface treatments have been applied to the PEEK, PPS and PEI-based composites in order to...
