Crystalline silicon (Si) nanowires are important building blocks in devices of photonics, quantum-dots, optoelectronics, and energy. Thermal annealing of metal-covered Si wafers gives rise to clean Si nanowires without metallic catalyst at the tip. The process does not need flammable or toxic gases....
