K. Kawabata et al., EFFECT OF SUBSTRATE-TEMPERATURE ON FILM GROWTH OF THE ORGANIC METAL (BEDT-TTF)(2)I-3, Journal of the Korean Physical Society, 31(3), 1997, pp. 431-434
The vacuum evaporation method was modified for thin films of the organ
ic charge-transfer complex (BEDT-TTF)(2)I-3. This modified evaporation
method made it possible to investigate the effect of the substrate te
mpearture on the film properties in detail. The thin films changed sys
tematically from the alpha-phase of (BEDT-TTF)(2)I-3 to the beta-phase
as the substrate temperature was raised from 40 degrees C to 60 degre
es C. This was caused not by the transformation of the alpha-phase to
the alpha(t)-phase but by the growth of two different phases. The morp
hology and the structure of the deposited films were also examined by
atomic force microscopy and X-ray diffraction.
