The orientations of TTF-TCNQ films co-evaporated onto several kinds of organic buffer layers were investigated. The c(*)-axis of TTF-TCNQ was normal to the substrates. However, the direction of the b-axis was random on CaF2 and cadmium-stearate LB film deposited CaF2 substrates. The b-axis of TTF-TCNQ evaporated on polytetrafluoroethylene (PTFE) rubbing layer arranged across the rubbing direction, but the film contained many grooves due to PTFE rubbing. TTF-TCNQ films on calcium-stearate/PTFE buffer layer had flat surface, even though the degree of the b-axis orientation was not high.
