Abstract

Silicon nucleation process was invesigated in melt KF-KCl-K₂SiF₆ on glassy carbon substrates at 675 ºС by chronoamperometric method. Using data of the chronoamperograms the linear dependence I – τ^3/2 was constructed. That fact testified the progressive nucleation mode of silicon. As seem from SEM micrographs silicon crystals obtained by a single pulse had different sizes, that also confirmed the progressive nucletion mode.

Keywords

method of chronoamperometry; glass-carbon substrate; electrochemistry, silicon
