Numerical Analysis of AgInSe2‐Based Thin‐Film Solar Cells Towards High Efficiency
In this work, SCAPS‐1D is used to numerically explore AgInSe2‐based thin‐film solar cells. Using CuS, WSe2, and AlSb as back surface field (BSF) layers with a CdS window improves carrier separation and built‐in potential. AgInSe2's promise for high‐performance, stable, and environmentally friendly solar applications is demonstrated by the optimised CdS/

Thermodynamic study of zinc antimonides by the electromotive force measurements
Zinc antimonides and phases based on them are of great interest as earth-abundant, low-cost, and environmentally friendly thermoelectric materials. The present work demonstrates the results of a thermodynamic study of the ZnSb and Zn4Sb3 compounds by a ...

Atomic hydrogen cleaning of GaSb(001) surfaces [PDF]
We show that the (001) surface of GaSb can be cleaned efficiently by exposure to atomic hydrogen at substrate temperatures in the range 400–470 °C. This treatment removes carbon and oxygen contamination, leaving a clean, ordered surface with a symmetric (

Discovery of Sustainable Energy Materials Via the Machine‐Learned Material Space
State‐of‐the‐art machine learning models used in materials science are shown to construct meaningful internal representations, which can be interpreted as a map of the material space from the viewpoint of the network. It shows how this map can be used to find alternative, e.g., more sustainable materials for important optical materials, such as ...

Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

Giant Carrier Mobility in Single Crystals of FeSb2
We report the giant carrier mobility in single crystals of FeSb2. Nonlinear field dependence of Hall resistivity is well described with the two-carrier model. Maximum mobility values in high mobility band reach ~10^5 cm^2/Vs at 8 K, and are ~10^2 cm^2/Vs

Active Learning‐Guided Accelerated Discovery of Ultra‐Efficient High‐Entropy Thermoelectrics
An active learning framework is introduced for the accelerated discovery of high‐entropy chalcogenides with superior thermoelectric performance. Only 80 targeted syntheses, selected from 16206 possible combinations, led to three high‐performance compositions, demonstrating the remarkable efficiency of data‐driven guidance in experimental materials ...

High spin polarization in the ferromagnetic filled skutterudites KFe4Sb12 and NaFe4Sb12
The spin polarization of ferromagnetic alkali-metal iron antimonides KFe4Sb12 and NaFe4Sb12 is studied by point-contact Andreev reflection using superconducting Nb and Pb tips.

Nonreciprocal Terahertz Propagation via InSb Topological Photonic Crystals
Addressing the challenge of high magnetic field requirements in conventional gyromagnetic materials, this article investigates indium antimonide (InSb) rod arrays operating at terahertz frequencies. By exploiting the synergy between the Voigt effect and the dispersive scaling properties, robust unidirectional propagation is achieved under a remarkably ...
