Graphene–aluminum nitride NEMS resonant infrared detector

Evaluate The Behavior of PIN infrared detector via COMSOL software

Infrared detectors can be used for a variety of applications such as: using in fiber-optic communications. Conventional technology for IR detectors is using p-i-n structure based on GaAs compound. This paper reports on the design and modeling of an IR detector using a p-i-n GaAs structure. Comsol software is used to simulate the model and the detector is discussed for terminal current, dopant p...

A titanium-nitride near-infrared kinetic inductance photon-counting detector and its anomalous electrodynamics

Infrared Detector Arrays for Astronomy

Use of infrared detector arrays in astronomy began roughly 20 years ago, and our detection capabilities in parts of this spectral range have doubled about every seven months since then. A variety of approaches are now used for detector arrays operating from 1 μm to 1 mm and beyond. They include direct hybrid arrays of InSb and HgCdTe photodiodes that operate from 0.6μm to 5μm, and of Si:As impu...

Infrared spectra of carbon nitride films

The assignment of the vibrational modes in amorphous carbon nitride (CN) films is discussed by considering CN films deposited using a variety of methods. The infrared (IR) spectra of CN show three main absorption bands. In hydrogenated CN samples, CH and NH groups give rise to stretching vibrations at 3000 and 3400 cm , respectively. A weaker sharp band is y1 x x observed approximately 2200 cm ...

Influence of resonant and non-resonant vibrational excitation of ammonia molecules in gallium nitride synthesis

Attempts on the selective promotion of gallium nitride (GaN) growth were investigated by deploying laserassisted vibrational excitation of reactant molecules, which deposits energy selectively into specific molecules and activate the molecules towards the selected reaction pathways. Laser-assisted metal organic chemical vapor deposition (LMOCVD) of GaN was studied using a wavelength-tunable CO2...
