Abstract:The correlations among the electrical properties, the EL2 concentration and the carbon acceptor concentration in undoped semi insulating LECGaAs are investigated quantitatively by use of optical absorption method and Van der Pauw method. Comparisons are made between the experiment results and those calculated from equation of neutrality charge and carrier statistics theory. It is found that other acceptors, except carbon, exist and play an important role in electrical compensation in this semi insulating material.
Keywords:GaAs Carbon EL2 Electrical Properties
