摘要

Chalcogenide (arsenic sulfide) nanowires have been successfully synthesized front As2S1 under near-equilibrium conditions via an evaporation-condensation process in evacuated glass ampoules. The as-synthesized rianowires were pure, nearly stoichiometric, and amorphous. The nanowires had diameters ranging from 40 to 140 nm and lengths tip to a few millimeters. Distinct joints of the crisscrossing nanowires indicate potential for forming structural networks. They hake been characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM). energy dispersive spectroscopy (EDS). Raman spectroscopy, and X-ray diffraction (XRD) to determine their structure, composition. and morphology, Selected area diffraction (SAD) in the TEM and XRD confirmed their amorphous nature. The As-S nanowires could make in ideal system for understanding the carrier transport and photonic properties in nanoscale for this family of materials (IV V compounds), Chalcogenide nanowires show promise for integrated nanoelectronics and biophotonics.
