Low Temperature Hall and Shubnikov - De Haas Effects.

Abstract

The goals of this program were to develop the facilities necessary to measure the quantum Hall effect and Shubnikov - de Haas effects at magnetic fields up to 9 Tesla and at temperatures down to 0.5 Kelvin or below. Theses goals were accomplished and AlGaAs/GaAs high electron mobility samples were measured, owing the effectiveness of the high fields and low temperatures. A 3He refrigerator was designed and constructed for this project and coupled with a superconducting magnet. A PC based computer control program was written in QuickBasic to control the experiment....
