Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>SiC_{<italic>x</italic>} nano dots and nano wires with sizes from 60 nm to approximately 2 µm were fabricated using liquid cell transmission electron microscope (TEM) technology. A SiCl₄ in CH₂Cl₂ solution was sealed between two pieces of Si₃N₄ window grids in an <italic>in situ</italic> TEM liquid cell. Focused 200 keV electron beams were used to bombard the sealed precursors, which caused decomposition of the precursor materials, and deposition of the nano materials on the Si₃N₄ window substrates. The size of nano dots increased with beam exposure time, following an approximately exponential relationship with the beam doses. Secondary electrons are attributed as the primary sources for the Si and C reduction. A nano device was formed from a deposited nano wire, with its electrical property characterized.</p> </abstract>
