Hydrostatic and uniaxial pressure generation using teflon cell container in conventional piston-cylinder device

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.
