Preparation of aligned Cu/sub 2/S nanowire arrays and their field emission properties

Large-area and well-aligned Cu/sub 2/S nanowire arrays were fabricated by gas-solid reaction. X-ray diffraction and scanning-electron microscopy (SEM) were employed to characterize the nanowire arrays. The Cu/sub 2/S nanowire arrays grown on copper film were 50-200 nm in diameter and several micrometers long. Also, the field emission characteristics of the nanowires were studied in this work.
