Wide bandgap semiconductor AlGaN alloys have been identified as key materials to fabricate solar-blind ultraviolet photodetectors (SBUV PDs). Herein, a self-driven SBUV polarization-sensitive PD (PSPD) based on semipolar (112̅2)-oriented AlGaN films is reported. Using the flow-rate modulation epitaxy method, the full widths at half maximum (FWHMs) for the obtained (112̅2) AlGaN along [112̅3̅] and [11̅00] rocking curves are 0.

Experimental potentiometric unified pH (pH) scale is presented in 1,2-dichloroethane (1,2-DCE). The scale was compiled using differential potentiometric measurements, carried out by pair-wise comparisons between solutions. Aqueous standard buffer solutions were used as anchor points, so that the obtained pH values are linked to (, are traceable to) the conventional aqueous pH scale and are expressed as values.

Key Laboratory of MEMS of Ministry of Education, School of Integrated Circuits, Southeast University, Nanjing 210096, China.
Metal-semiconductor contact plays a significant role in devices such as transistors, photoemitters, and photodetectors. Here, the AuIn alloy contact gives a state-of-the-art low (contact resistance) in GeSe devices. The of GeSe-AuIn is measured to be 25 kΩ μm under channel carrier concentration around = 2.
