Abstract

Diffusely reflecting metal oxide, preferably titanium dioxide, coatings are prepared on substrates by atomic layer epitaxy. Successive pulses of a hydrolyzable metal chloride and water are introduced at pressures in the range of about 180-1250 and about 150-650 millitorr, respectively, the pulse length being effective to produce a coating with an average thickness of about 15-25 .ANG.ngstroms during a single pulse pair.
