Abstract

Post anneals of short duration at high temperature can improve the quality of CaF//2 films grown by molecular beam epitaxy (MBE) on Si(100). Anneals at 1100 degree C for 20 sec in Ar improved the ratio of backscattered 1. 8 MeV He**4 ions in the aligned to random direction from as-grown values of . 07 to . 26 to post post-anneal values of . 03 to . 045. The post-annealed films also show improved resistance to chemical etching and mechanical stress and increased dielectric breakdown voltages.
