Conductivity Experiment

Conductivity and Photoconductivity Transients Measurement Systems:

This facility consists of a 700 ps nitrogen pumped dye laser system, a sub-nanosecond pulse generator, 1/4 m monochromator, a closed-cycle He refrigerator with temperature range between 10 - 650E K, and a sampling scope (Tektronics).  The facility is dedicated to the studies of the efficiency and response speed of UV detectors and drain current transient characteristics of transistors.
