Abstract
Recombination via deep level centers within a delta doped sheet in GaAs diodes is investigated as a function of deep level energy and local sheet position within the junction. Current-density versus voltage (jV) characteristics of pn-junctions are calculated varying the sheet position and energy of a single level, and a double level deep center (Ti). With homogeneous photogeneration, the changes in open circuit voltage Voc and fill factor of photodiodes are determined as a function of such delta doping. Schottky barriers on MBE-grown GaAs with a planar thin Ti doped sheet are examined by capacitance-voltage (CV) measurements. The corresponding charge profiles N(W) are compared with modeling results.
