Abstract
Two kinds of mounds or hillocks have been found on BaTiO3 single crystals after etching. Rounded, flat‐topped hillocks were found after etching with 1% HF for 30 sec at room temperature. These hillocks were found where a 180° domain wall had been left for several days and had been removed shortly before etching. Their behavior can be explained by the ad hoc assumption that negative charges are attracted to the 180° domain wall at the crystal surface. Mounds shaped like Egyptian pyramids were found after etching BaTiO3 single crystals for 30 min in H3PO4 at 155°C. The edges between pyramidal faces always project onto the crystal surface (a 100 plane) in 110 directions.This publication has 3 references indexed in Scilit:
