Thesis (Ph. D.)--University of Wisconsin, 1908.

The steps to be taken in developing a technique of growing single crystals are outlined. Two theories on crystal growth are lightly treated. The record of the experimental work done includes the following. The development of an axial temperature gradient in a furnace to operate in the temperature ranges 600°C to 1400°C is discussed. A controller to control the temperature of this furnace to [formula omitted] is developed. A recording unit to record the temperature variations with time (or with position in the furnace) is incorporated. The considerations for preparing and testing pure PbTe are discussed. This include a table of the spectral lines of tellurium, compiled from the M.I.T. Table of Wavelengths. A technique for producing a single crystal is outlined. The attempts to produce a single crystal of PbTe are described. The degrees of success and failure are discussed. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

The temperature and stress fields for the Vertical Bridgman growth of CdTe were calculated using the finite element method. The critical resolved shear stress (CRSS) of CdTe was measured at elevated temperatures. The measured CRSS and the calculated shear stress were compared to determine the onset of dislocation formation in the crystal. The effect of furnace gradient, crucible velocity, hot furnace temperature and cold furnace temperature on the solid/liquid interface shape and calculated resolved shear stress were examined using the model. Etch pit density measurments were carried out in order to verify the stress model. / Applied Science, Faculty of / Materials Engineering, Department of / Graduate
