The study of the electrical properties by photoabsorption and photoconductivity kinetics measurements is already a classical method in the analysis of semiconducting materials. Likewise, the Beam Induced Current mode of Scanning Microscopy is a well established technique in experimental physics, in spite of its recent birth, when dealing both with an electron beam (EBIC) and a light beam (LBIC).
