Optical absorption in silicon monoxide

I. R. Rawlings

Measurements of the transmission spectra of thick silicon monoxide films are reported, and from these the absorption coefficient of silicon monoxide is calculated as a function of wavelength. The results obtained are compared with the predictions of a simple theoretical model.
