An infrared Fourier spectrophotometer has "been set up in the solid state laboratory of the University of British Columbia.
A cryostat has been built and adapted to the spectrometer.
A computer program to analyze the data and plot the spectrum has been written.
As a demonstration of the system's capability, the transmission spectrum from 40 cmˉ¹ to 330 cmˉ¹ of boron doped silicon was obtained for the sample at liquid helium temperature. This spectrum was compared to earlier work done by Colbow in the region 240 cmˉ¹ to 330 cmˉ¹.
A spectrum of boron and indium doped silicon was Investigated in the hope of finding Bˉ and In⁺ ionized centres. These were not found at the impurity concentrations and temperatures used.
A transmission spectrum of intrinsic silicon at liquid helium temperature was obtained for the region 40 cmˉ¹ to 330 cmˉ¹
A comparison of the above spectra suggests that the low energy tail of the boron doped and boron and indium doped samples is due to a frequency dependent value of reflectivity as Is seen from the spectrum for intrinsic silicon. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
