Antimony‐Incorporated Vertically Aligned Cu2O Photoelectrodes for Efficient Solar‐Driven Photoelectrochemical Water Purification

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This work demonstrates a simple and scalable electrochemical deposition strategy to fabricate Sb‐incorporated Cu2O photocathodes with preferential (111) crystal orientation and vertically aligned grain boundaries. Unlike conventional Cu2O, the optimized Sb:Cu2O electrode exhibits a high photocurrent density and enables complete degradation of methyl ...

Leakage currents and capacitances of thick CZT detectors [PDF]

2007 IEEE Nuclear Science Symposium Conference Record, 2007
The quality of Cadmium Zinc Telluride (CZT) detectors is steadily improving. For state of the art detectors, readout noise is thus becoming an increasingly important factor for the overall energy resolution. In this contribution, we present measurements and calculations of the dark currents and capacitances of 0.5 cm-thick CZT detectors contacted with ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Investigating synthesis of Cu2ZnSn(Se1-x,Sx)4 for values of 0≤x≤1 by S for Se substitution and direct sulphidisation of metallic precursors [PDF]

, 2011
Thin layers of Cu2ZnSn(Se1-x,Sx)4 were produced by selenisation and subsequent sulphur substitution of DC sputter-deposited metallic CZT precursors on soda-lime glass. Values of x=(0, 0.07, 0.12, 0.17, 0.28, 1) were measured by EDS.

Unassisted Photoelectrochemical Hydrogen Production Coupled with Selective Glucose Oxidation Using Metal Halide Perovskite Photoanodes

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
A metal halide perovskite‐based photoanode integrated with a CoNiFe layered double hydroxide (LDH) cocatalyst is reported for selective glucose oxidation reaction (GOR), achieving simultaneous and unassisted photoelectrochemical hydrogen production. This system delivers high photocurrent density, excellent Faradaic efficiency of GOR, and strong techno ...
