摘要：
The crystallinity, preferential ordering, and interfacial stability of 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HATCN) thin films inter-connected with organic/inorganic multilayers have been investigated. In the region close to the organic-organic interface, HATCN formed a low crystalline order with a substantial amorphous phase. As film growth continued, HATCN stacked to the high crystalline ordered phase. After the sputtering deposition of the indium zinc oxide (IZO) layer on top, the volume fraction of the preferentially ordered region of HATCN increased without any structural deterioration. In addition, the HATCN surface was kept quite stable by preserving the sharp interface between the HATCN and sputtering-deposited IZO layers. (C) 2015 The Japan Society of Applied Physics
