In this article, a single step, chemically synthesized dumbbell-shaped ZnO microcrystal has
been utilized to fabricate UV photodetectors and highly selective H 2 gas sensors. The …

We study the effect of temperature and doping in Si-based GeSn heterojunction
phototransistors (HPTs) for low-power-consuming, low-cost, and high-speed mid-infrared …

Silicon carbide (SiC) semiconductors with a wide bandgap have attracted much attention
because they can endure harsh environments and high temperatures. SiC photodetectors …

III-nitride resonant cavity-enhanced Schottky barrier photodetectors were fabricated on 2 µm
thick GaN templates by radio frequency plasma-assisted molecular beam epitaxy. The …

A comparative study on the photoresponse of zinc oxide nanowires in direct-current (DC)
and alternating-current (AC) domains is presented. Zinc oxide ultraviolet photodetectors …

A suspended WO_3-gate AlGaN/GaN heterostructure photodetector integrated with a micro-
heater is micro-fabricated and characterized for ultraviolet photo detection. The transient …

In most past studies, MSM (Metal–Semiconductor–Metal) detectors with the varying area
have been investigated for varying number of fingers (metal electrodes) of equal width (W) …

Optical spectroscopy is one of the most widely used analytical techniques in science and
engineering. Miniaturizing an optical spectrometer can allow for a portable and handheld …

Yttria-stabilized zirconia (YSZ) is a widely used ceramic material in solid oxide fuel cells,
oxygen sensors, and sensing applications due to its high ionic conductivity, chemical …
