Electronic structure of crystalline binary and ternary Cd-Te-O compounds

, 2004
The electronic structure of crystalline CdTe, CdO, $\alpha$-TeO$_2$, CdTeO$_3$ and Cd$_3$TeO$_6$ is studied by means of first principles calculations. The band structure, total and partial density of states, and charge densities are presented.

Balloon-borne coded aperture telescope for arc-minute angular resolution at hard x-ray energies [PDF]

, 1996
We are working on the development of a new balloon-borne telescope, MARGIE (minute-of-arc resolution gamma ray imaging experiment). It will be a coded aperture telescope designed to image hard x-rays (in various configurations) over the 20 - 600 keV ...

Bridging Scales in Flexible Perovskite Solar Cells: Mechanisms, Interfaces, and Applications

Advanced Science, EarlyView.
This perspective focuses on the advancement of flexible perovskite solar cells (f‐PSCs) from the energetic point of view, and summarizes the mechanisms, material characteristics, device performance, and failure mechanisms across the microscopic, mesoscopic, and macroscopic scales through mechanical energy dissipation theory.

Hall-effect and resistivity measurements in CdTe and ZnTe at high pressure: Electronic structure of impurities in the zincblende phase and the semi-metallic or metallic character of the high-pressure phases

, 2010
We carried out high-pressure resistivity and Hall-effect measurements in single crystals of CdTe and ZnTe up to 12 GPa. Slight changes of transport parameters in the zincblende phase of CdTe are consitent with the shallow character of donor impurities ...

Modeling and Verification of 1/f Noise Mechanisms in FAPbBr3 Single‐Crystal X‐Ray Detectors

Advanced Electronic Materials, EarlyView.
We demonstratethat surface‐trap‐induced carrier number fluctuations are the dominantmechanism in FAPbBr3 Schottky devices, a conclusion supported by thedistinct defect profiles revealed by Drive‐Level Capacitance Profiling (DLCP). Throughnoise contribution decomposition, it is found that the 1/f noise of thedetector is the key noise source affecting ...

Enhancing high-energy powder X-ray diffraction applications using a PILATUS4 CdTe detector

Journal of Synchrotron Radiation
Hybrid photon counting detectors have significantly advanced synchrotron research. In particular, the introduction of large cadmium telluride-based detectors in 2015 enabled a whole new range of high-energy X-ray measurements.

Development of Back and Front Contacts for CdTe Layer in Tandem Flexible Photoelectric Converters on Basis of CdTe/CuInSe2

International Journal of Photoenergy, 2019
By the method of nonreactive high-frequency magnetron sputtering on Upilex polyimide films, transparent and conductive layers of ITO were obtained. These layers, after high-temperature annealing, at temperatures typical for the solar cell formation, had ...

Timing Offset Calibration of CZTI instrument aboard ASTROSAT

, 2018
The radio as well as the high energy emission mechanism in pulsars is yet not understood properly. A multi-wavelength study is likely to help in better understanding of such processes.
