Sun, J. (author), Sokolovskij, R. (author), Iervolino, E. (author), Santagata, F. (author), Liu, Zewen (author), Sarro, Pasqualina M (author), Zhang, Kouchi (author)A suspended AlGaN/GaN high electron mobility transistor (HEMT) sensor with a tungsten trioxide (WO 3 ) nanofilm modified gate was microfabricated and characterized for ppm-level acetone gas detection. The sensor featured a suspended circular membrane structure and an integrated microheater to select the optimum working temperature. High working...journal article 2019

(author), Yu, Hongyu (author), Sarro, Pasqualina M (author), Zhang, Kouchi (author)AlGaN/GaN high electron mobility transistor (HEMT)-based sensors with catalytic platinum gate were micro-fabricated on commercially available epitaxial wafers and extensively characterized for ppm level hydrogen sulfide (H<sub>2</sub>S) detection for industrial safety applications. High operating temperature above 150 °C enabled large signal...journal article 2018

(author), Zhang, Kouchi (author), Sarro, Pasqualina M (author), Zhang, Guoyi (author)Purpose: The purpose of this paper is to demonstrate a novel 3D system-in-package (SiP) approach. This new packaging approach is based on stacked silicon submount technology. As demonstrators, a smart lighting module and a sensor systems were successfully developed by using the fabrication and assembly process described in this paper. Design...journal article 2018
