We report the successful growth of pseudomorphic, trigonal structured HoF3 insulating layers, stable at room temperature, on the Si(111) surface. Normally the tysonite structure is only stable at temperatures above 1070 °C [R. E. Thoma and G. D. Brunton, Sov. Phys. Crystallogr. 18, 473 (1966)]. A phase transition to the lower‐temperature orthorhombic structure is observed for a thickness of around 12 Å, consistent with the relaxation of elastic strain in the insulating layer.
