Probe-corrected scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy were used to characterize the inter- and intraparticle compositional inhomogeneity of multinary Cu2ZnSnS4 (CZTS) nanoparticles. CZTS nanoparticles were …
Wurtzite-derived copper−zinc−tin sulfide nanoparticle films were observed to undergo a phase transformation to a kesterite phase when exposed to Se vapor at 500 °C. The resulting dense and selenized Cu2ZnSn(S,Se)4 (CZTSSe) films were found to have the …
This paper presents a new approach to synthesizing self-aligned, uniform single-crystal cupric oxide (CuO) nanowires on a Cu-based multilayer on SiO2/Si. The key is to introduce CoWP as a nanofilter to catalyze CuO-nanowire synthesis simply by …
