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 AlGaAsGaAs 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....
