THE EFFECT OF PRESSURE ON OPTICAL PROPERTIES OF SEMICONDUCTORS.
Abstract
This report describes measurements of the effect of hydrostatic pressure on optical properties of group 4 and group 3-5 semiconductors in the infrared, visible, and near-ultraviolet regions of the spectrum. The results of these experiments provide evidence in support of the following empirical rule inferred previously from earlier work on pressure effects: Energy separations of corresponding electronic states in related materials change with pressure at nearly the same rate. The correlation between pressure coefficient and transition type permits investigation of electronic energy-band structure by means of optical-pressure experiments. This approach was taken to study the band structure of GaP. (Author)
