TCAD-Based Analysis on the Impact of AlN Interlayer in Normally-off AlGaN/GaN MISHEMTs with Buried p-Region

With the growing demand for more efficient power conversion and silicon reaching its theoretical limit, wide bandgap semiconductor devices are emerging as a potential solution. For instance, Gallium Nitride (GaN)-based high-electron-mobility…

Tuning the coercive field of strontium M-type hexaferrite nanopowders via pH control

Single-phase strontium M-type hexaferrite (SrFe12O19) nanopowders were successfully synthesized via a citrate precursor sol–gel method. This study investigates the effect of pH variation in the precursor solution on the structural, morphological,…

Ellipsometry of surface acoustic waves using 3D vibrometry for viscoelastic material characterization by the estimation of complex Lamé coefficients versus the frequency

Surface acoustic waves (SAW) are adequate regarding material characterization because they have low geometric attenuation compared to bulk waves. SAW can be generated easily by normal excitation using contact transducers or power lasers and have…

An innovative method for the objective comparison of the performance of active control devices

In the active control literature, the question of how to objectively and comprehensively compare system performance has received little attention. In most cases, comparisons are only made on a paper-specific application and cannot be extended to new…
