Abstract (in Japanese) (See Japanese page) 
(in English) It has been taken for granted that molecules in organic vacuum-deposited amorphous films are randomly oriented and the films themselves are isotropic. Here, however, the authors demonstrate horizontal orientation of long or planar molecules in organic amorphous films using variable angle spectroscopic ellipsometry and cutoff emission measurement. The molecular orientation was observed in films on many kinds of underlying layers and even in doped films. It was found that there is a correlation between molecular structures and orientation order parameters and that the orientation affects electrical characteristics of the films. The horizontal molecular orientation can be utilized to improve light out-coupling efficiencies and carrier transport characteristics of OLEDs.
