Facile Microwave-Assisted Synthesis of Klockmannite CuSe Nanosheets and Their Exceptional Electrical Properties

Klockmannite copper selenide nanosheets (CuSe NSs) are synthesized by a facile microwave-assisted method and fully characterized. The nanosheets have smooth surface and hexagonal shape. The lateral size is 200-500 nm x 400-800 nm and the thickness is 55 +/- 20 nm. The current-voltage characteristics of CuSe NS films show unique Ohmic and high-conducting behaviors, comparable to the thermally-deposited gold electrode. The high electrical conductivity of CuSe NSs implies their promising applications in printed electronics and nanodevices. Moreover, the local electrical variation is observed, for the first time, within an individual CuSe NS at low bias voltages (0.1 similar to 3 V) by conductive atomic force microscopy (C-AFM). This is ascribed to the quantum size effect of NS and the presence of Schottky barrier. In addition, the influence of the molar ratio of Cu2+/SeO2, reaction temperature, and reaction time on the growth of CuSe NSs is explored. The template effect of oleylamine and the intrinsic crystal nature of CuSe NS are proposed to account for the growth of hexagonal CuSe NSs

Physical Vapor Growth of Ultralong Microwires of Copper Phthalocyanine on 1-Butyl-3-methylimidazolium Tetrafluoroborate Ionic Liquid

Ultralong microwires of CuPc were prepared by physical vapor deposition on [BMIM]BF4 ionic liquid. The as-prepared microwires are highly pure and single crystals. Moreover, this method is applicable to prepare microwires of NiPc and CoPc

The as-obtained AgTCNQ nanowires are very long and have controlled phase and smooth surfaces. The diameters of nanowires are 100-200 nm and the lengths are 10-100 mu m. Moreover, prototype devices are fabricated on the basis of individual AgTCNQ nanowires and display good electrical switching. The facile synthesis and unique electrical properties of AgTCNQ nanowires paves the way for the future nanoscale electronics, especially in ultrahigh-density information storage.
