Abstract：
Lithium fluoride(LiF) cluster-based films deposited on monocrystalline silicon with vaporzation/ condensation method have been studied by low energy positron beam and the S parameters and the effective lengths of diffusion (L _eff) in position annihilation were measured. The influences on the microstructure of LiF cluster-based films by the conditions of preparation, such as the temperature of tho substrate, the rate of tho vaporization and the partial pressure of Ar are discussed.
