Sensor and Device Characteristics

Magneto-optical characterization equipment:  Oxford Instruments superconducting magnet with optical access both parallel and perpendicular to the magnetic field.  The system is capable of producing fields up to 7 T and the sample temperature can be set anywhere from 2 K to 300 K (-456°F to 80°F).  A spectroscopic light source provides monochromatic light in the spectral range from 200 nm to 1800 nm for reflection and transmission measurements.  Additionally, an Argon ion laser is available as an excitation source for photoluminescence measurements.
