In this paper we describe a method for controlling both the residual stress and the through-
thickness stress gradient of aluminum nitride (AlN) thin films using a multi-step deposition …

This article reports a gallium nitride (GaN)-based switchable bulk acoustic wave (BAW)
resonator with low dc switching voltage and through GaN vias. The low switching voltages …

This paper reports on the first demonstration of GaN-based switchable Lamb wave delay
lines with> 40 dB ON/OFF ratio at several gigahertz frequency range. The high-density two …
