Abstract
A surface treating method of single crystals by which single crystals for substrates having finished surfaces showing pit-free and atomic scale step structures are obtained by treating the {100}-plane surfaces of single-crystal SrTiO.sub.3 substrates by dissolving two-dimensional-lattice atomic layers forming the surfaces one layer by one layer by using a fluorine-based acidic solution (maintained at >35.degree. C. in temperature and <4 in pH) as a solution A and water as a solution B by alternately immersing the substrates in the substrates in the solution A and B.
