Abstract

A tomographic method of determining a 3D map of a charge collection efficiency in a charge carrier-separating sample. The method includes positioning the sample in a beam path, scanning the sample to measure the beam induced current and/or voltage for a plurality of locations, assigning a coordinate location for each of the plurality of locations, and applying a tomographic image reconstruction algorithm to generate a 3D map of the charge collection efficiency based on the assigned coordinate locations.
