|In situ liquid cell TEM technology has been used to study nano material deposition by means of liquid phase electron beam induced deposition (LP-EBID). The electron beam energy varies from 100 keV to 200 keV. Firstly, using a HAuCl 4 solution as the precursor and under a broad electron beam, scattered gold nano particles of 14-72 nm have been deposited. Then using SiCl 4 and SiCl 4 in CH 2 Cl 2 solutions as the precursors and under well focused electron beam irradiations, localized Si and SiC x nano dots and nano wires have been developed. The size and shape of the Si and Six nano structures can be well controlled by adjusting the deposition parameters, and the nanostructures are found to attach well to the Si 3 N 4 window substrates of the liquid cell, showing good promise for future nanoelectronic device developments. Besides these inorganic nanostructures, the in situ TEM technology has been further successfully used to perform nano characterizations on organic composites and biological cells.|
