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.
