摘      要：This article summarizes work at the Laser Thermal Laboratory and discusses related studies on the laser synthesis and functionalization of semiconductor nanostructures and two-dimensional(2D)semiconductor *** has been carried out on the laser-induced crystallization of thin films and *** in situ transmission electron microscopy(TEM)monitoring of the crystallization of amorphous precursors in nanodomains is discussed *** directed assembly of silicon nanoparticles and the modulation of their optical properties by phase switching is *** vapor-liquid-solid mechanism has been adopted as a bottom-up approach in the synthesis of semiconducting nanowires(NWs).In contrast to furnace heating methods,laser irradiation offers high spatial selectivity and precise control of the heating mechanism in the time *** attributes enabled the investigation of NW nucleation and the early stage of nanostructure ***-and shape-selective,on-demand direct integration of oriented NWs was *** of discrete silicon NWs with nanoscale location selectivity by employing near-field laser illumination is also reported *** the properties of 2D transition metal dichalcogenides(TMDCs)by modulating the free carrier type,density,and composition can offer an exciting new pathway to various practical nanoscale *** situ Raman probing of laser-induced processing of TMDC flakes was conducted in a TEM instrument.
