B. Solution-Liquid-Solid Growth of Indium Phosphide Fibers from Organometallic Precursors: Elucidation of Molecular and Nonmolecular Components of the Pathway
Solution-phase organometallic syntheses of semiconductors are used for the growth of high-quality quantum dots,1-3 and are potentially useful for the deposition of semiconductor materials on thermally sensitive substrates such as polymers
curve shift toward applied voltage because the movement of charges is determined by applied voltage(-,+). It is known that mobile charges are generated when dielectric material has the impurities such as Na ion.
The term fast interface state refers to the fact that these defects can change their charge state relatively fast in response to changes of the gate bias. As the surface potential in a

4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer
