Abstract

Single-crystalline Cu2−x Se nanowires with high aspect ratio on copper substrate have been achieved by a simple hydrothermal route. Based on in situ TEM studies, while utilizing integrated STM holder measuring their electrical conductivities, it is confirmed that single-crystalline Cu2−x Se nanowire was very good match the semiconducting characteristic. An electron source device using as-prepared Cu2−x Se nanowires on the Cu substrate has been first fabricated, which shows excellent field emission (FE) properties: the emitting current density as high as 0.83 μA/cm2 at an applied field of 5.5 V/μm, suggesting that the Cu2−x Se nanowire may be potentially applied in the vacuum microelectronics industry.
