  Deformation of copper single crystals: Comparison of …

  202091 · Abstract A combined experimental and numerical study on deformation behaviour of single crystal copper is presented in this paper. High purity copper single crystals were fabricated and subjected to uniaxial compression loading at quasi-static strain rate. The stress-strain responses along four different crystallographic orientations were …

  Origin of Hole‐Trapping States in Solution‐Processed Copper…

  2023620 · In article number 2209504, Pichaya Pattanasattayavong and co-workers, report that X-ray absorption spectroscopy reveals the incomplete coordination environment around Cu (I) centers in CuSCN which can be associated with SCN − vacancies acting as hole-trapping states. Doping with an optimal amount of I 2 leads to defect-healing and a …
