HgCdTe sampling circuit

Electronics Letters, 1990
The demonstration, using HgCdTe MISFETs, of a sampling circuit with output buffer amplifier is reported. Using the circuit, correlated double sampling is demonstrated at speeds typical of those required for focal plane arrays. Using a swept sine input, the circuit's transfer function is verified.

Disclosing the carrier distributions in ion-implanted HgCdTe p–n junctions with scanning capacitance microscopy

AIP Advances
Ion implantation doping is the primary method for forming p–n junctions in HgCdTe. However, the doping and activation in HgCdTe are influenced by various complex factors, leading to inconsistencies between the actual carriers and the distribution of ...

High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit [PDF]

, 2011
High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties

Advanced Functional Materials, EarlyView.
High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen
