Facilities, equipment, and other resources:
· My group's lab space includes rooms 001, 003, 308, and 504 in the Physical Science Center building and room 2 in the Neutron Generator building.
Magnets and Cryogenics:
Oxford Instruments 16-Tesla (64mm bore) Teslatron system with He4 and He3
(T = 280mK to 400K).
· Cryogen free 2.8K/1.2T system consisting of a Cyromech pulsed-tube refrigerator in the bore of a GMW 3473 water-cooled electromagnet (with 3" and 6" pole faces, adjustable gap, and fields up to 2T).
· Other dewar stations with smaller magnets (up to 5 Tesla) and a 40K closed-cycle helium refrigerator.
· Pulsed current and voltage sources (compliance voltages up to 400 V, currents up to 500 A), high-speed high-CMRR differential amplifiers, and Labwindows acquisition and waveform analysis tools. Real-time current-voltage correlation on a sub-nanosecond time scale.
· Digital storage oscilloscopes including LeCroy 204xi (200 GS/s RIS sampling rate, 4-channel), LeCroy LT322 (10 GS/s RIS, 2-channel), and LeCroy 7314 (2 GS/s RIS, 4-channel) plus other scopes.
· Usual complement of other electronic instrumentation (lock-in amplifiers, current/voltage sources, digital multimeters, etc.)
Sample preparation and characterization:
· Electron-beam lithography: Nabity NPGS system (40 nm resolution).
