The magnetic field induced metal insulator transition in doped                  semiconductors will be investigated by combined transport and far               infrared spectroscopic measurements.  The transport measurements                will be used to determine the critical field for the metal                      insulator transition and to investigate interaction and weak                    localization effects in the metallic state and the activated                    conductance in the insulating state.  The spectroscopic                         measurements will be used to investigate the electronic structure               of the systems away from the Fermi energy.  The transformation of               the cyclotron resonance and spin resonance signals on the                       metallilc state to the impurity transitions in the insulating                   state will be investigated.  These studies are on materials of                  importance to high speed opto-electronics.  This program is a                   collaborative effort between Professor Shayegan at Princeton                    Professor Drew at Maryland.                                                                                                                                     These studies are on material of high technological importance                  and related to high speed opto-electronic.
