Magneto-Optic Studies of Semiconductor Structures At Hydrostatic Pressure an d Low Temperature.
Abstract
We developed an unique experimental system to perform optical investigations of semiconductor materials in environments generally beyond the capability of other techniques. Using the solid helium pressure generating method and a superconducting magnet, we performed laser induced luminescence studies on a variety of structures at low temperature (less than or equal to 4K), high hydrostatic pressure, and high magnetic field. A quartz fiber was utilized to provide an optical path to and from a sample subjected to values of the external parameters. The use of the fiber alleviated the need for pressure chamber windows and concern for the transmissivity of the pressure medium, and allowed investigations over a frequency range limited only by the optical properties of the fiber.
