This work presents a multi-parameter water quality sensor system based on dual-gate thin-film transistor (DG-TFT) for accurate aquatic monitoring, targeting pH, dissolved oxygen (DO), and temperature.

This work presents an E-mode GaN lateral superjunction p-GaN gate HEMT (SJ-HEMT). The superjunction is constructed by alternative p-/n-pillars along the direction perpendicular to the current flow.
