Topology of obliquely coated silicon monoxide layers

摘要

Silicon monoxide layers, coated at oblique angles of 45deg;ndash;87deg; onto indium oxide coated glass substrates, are examined by TEM for angularly dependent surface topology. rsquo;rsquo;Striationsrsquo;rsquo; observed at angles near 81deg; are discussed in terms of the aligning influence that these features exert upon nematic liquid crystals. Included are photomicrographs of these striations as well as of a rsquo;rsquo;scalersquo;rsquo; feature observed at angles greater than 83deg;. Existence of the rsquo;rsquo;scalersquo;rsquo; feature is correlated to previously observed asymmetric diffuse diffraction effects.
