ABSTRACT
A spatially resolved electron beam technique, remote contact electron beam induced current, has been developed to detect and map charge-separating defects in HgCdTe with two remote sample contacts. This technique, characterized by a high spatial resolution, ∼1 μm, and a high sensitivity (signal/noise) to fields produced by inclusions, damage, dislocations, strain, p-n junctions, and possibly compositional (band gap) and doping variations, shows promise for analyzing materials, passivation coatings, and diode arrays without making contacts to the individual devices.
