Description

A thin film of Hf was deposited (10 nm) on silicon (111) substrate and its structural behavior with annealing was investigated with Time Differential Perturbed Angular Correlation (TDPAC) technique. Thin film was prepared by Ion Beam Sputtering method. The probe 181Hf/181Ta for TDPAC study was generated by neutron irradiation of the Hf thin film. Results indicate that the HfO2 thin film remains amorphous till the annealing temperature of 1073K. However a small fraction (25%) was converted into crystalline HfO2 in monoclinic phase when annealed at 1273K. Formation of hafnium silicide (HfSi2) at 1273K might also be inferred from the results.
