Paper Abstract

It has been found that alkali metal elements can be diffused into silicon and germanium. The infrared absorption spectra of these impurities have been measured using a Fourier transform spectrometer. Unlike the donor behavior of lithium in both silicon and germanium, the spectra of sodium show that it is a donor in silicon while an acceptor in germanium. It has also been found that the sodium spectrum in silicon is strikingly similar to that of lithium. Possible reasons for this unexpected result are discussed.
