Abstract

original image

A several-hundred Ångstrom thick ordered crystalline organic heterojunction consisting of copper phthalocyanine (CuPc) and 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) is grown by organic vapor phase deposition (OVPD) on a template alkali- halide substrate. This method of low-temperature thin-film templating combines the control of film growth with crystalline ordering approaching that of organic single crystals, producing potentially useful heterojunctions for high efficiency organic thin-film devices.
