Abstract
A technique has been evolved to generate hydrostatic and uniaxial stress regimes, using a Teflon cell as a container in a conventional piston‐cylinder device. Details of the technique and calibration procedure are described. The possibility of using high resistivity as‐grown n‐GaAs for pressure measurement is indicated. Piezoresistive effects in oriented n‐Si plates were used to determine the nature of stress distribution in the pressure medium. The usefulness of the technique to semiconductor studies is pointed out.
