Abstract:
Optimum conditions for ion implantation and subsequent annealing for the fabrication of NiSi$_2$/Si (111) nanofilms with a thickness of 3.0 – 6.0 nm are determined. It is demonstrated that the energy-band parameters and optical properties typical of thick NiSi$_2$ films start to set in at $d$ = 5.0 – 6.0 nm.
