Research Status

    Dr Luo has developed a novel method to fabricate ordered arrays of nanowire/tube heterojunctions and demonstrated the structure-property relationship in some of the heterojunctions by electron microscopy and electrical measurement. He has proved the imaging mechanism of individual single-walled carbon nanotubes (SWNTs) in scanning electron microscope and measured the secondary electron emission properties of individual SWNTs and graphene for the first time. It is found that the secondary electron yield of SWNTs is ulatrhigh, while that of graphene is ultralow. Dr Luo has realized plucking individual SWNTs point by point, and discovered the linear magnetic-field dependence without saturation in the magnetoresistance of silicon with low supply voltages and applied currents. His current researches involve fabrication, structural characterization, property measurement and analysis of nanotubes, nanowires, graphene, single-/few-layer MoS2, nanoheterojunctions and non-magnetic semiconductors as well as their devices for electronics, mechanics, energy conversion and magnetoresistance.
