Abstract:
Properties of Co–Si thin films produced by thermal treatment of Co and Si layers are studied in this article. Co/Si layers were produced by chemical vapor deposition. The two-layer structure was annealed at elevated temperatures for the formation of cobalt silicide. Thermoelectric properties of the film structures were investigated in the temperature range 300–800 K. Temperature dependences of thermopower and resistivity as well as structural data indicate the formation a multilayer structure with Si-rich and Co-rich layers.
