Environmentally benign synthesis of high-quality, band gap-tunable, homogeneous Te/Se alloyed nanowires†
Abstract
Ultrathin trigonal Te/Se alloyed nanowires with a tunable composition and band gap were fabricated using a nonhazardous reducing agent, ascorbic acid. The as-synthesized nanowires displayed a tunable direct band gap (3.39 to 3.78 eV) and indirect band gap (1.99 eV to 2.93 eV).
