Thermal dynamics of Au-Fe pair in silicon

Deep level transient spectroscopy technique has been used to study the thermal dynamics of Au-Fe pairs in silicon during isochronal annealing. The formation and dissociation energies of an Au-Fe pair has been calculated by counting the number of pairs formed during each annealing. The respective energies of the Au-Fe pair are found to be ∼0.36 eV and ∼0.46 eV. The pairing of Au− and Fei+ takes place under predominant electrostatic forces.
