Ferroelectric HEMT Reconfigurable Transistor (U. of Michigan)


A new technical paper titled "Fully epitaxial, monolithic ScAlN/AlGaN/GaN ferroelectric HEMT" was published by researchers at University of Michigan. “We can make our ferroelectric HEMT reconfigurable,” That means it can function as several devices, such as one amplifier working as several amplifiers that we can dynamically control. This allows us to reduce the circuit area and lower the... » read more

Making BaZrS3 Chalcogenide Perovskite Thin Films by Molecular Beam Epitaxy


Abstract: We demonstrate the making of BaZrS3 thin films by molecular beam epitaxy (MBE). BaZrS3 forms in the orthorhombic distorted-perovskite structure with corner-sharing ZrS6 octahedra. The single-step MBE process results in films smooth on the atomic scale, with near-perfect BaZrS3 stoichiometry and an atomically-sharp interface with the LaAlO3 substrate. The films grow epitaxially via tw... » read more

RF GaN Gains Steam


The RF [getkc id="217" kc_name="gallium nitride"] (GaN) device market is heating up amid the need for more performance with better power densities in a range of systems, such as infrastructure equipment, missile defense and radar. On one front, for example, RF GaN is beginning to displace a silicon-based technology for the power amplifier sockets in today’s wireless base stations. GaN is m... » read more
