Abstract:

A Fourier transform spectroscopy apparatus has been constructued. This apparatus uses photothermal ionization to probe the energy level structure of shallow impurities in semiconductors. The present form of the apparatus, and progress made in modifying it to increase its resolution are described in detail. An account of our immediate and possible furture applications of the apparatus is given. Author
