J. Kyokane et al., EFFECTS OF ION-BEAM IRRADIATION ON ELECTRICAL-PROPERTIES OF LANGMUIR-BLODGETT (LB) FILMS, Synthetic metals, 71(1-3), 1995, pp. 2217-2218
The charge transfer complex (TCNQ complex) LB films were fabricated by
using the Moving-Wall method. Among various donors, N-isopropyl 4,4'b
ipyridinum was prepared and TCNQ complex of different molar ratios of
the acceptor and donor were synthesized. The TCNQ complex LB films wer
e deposited onto glass as Y-type films. The conductivity of multilayer
s formed from the TCNQ complex was about 10(-3) S/cm in the plane of t
he films. The conductivity of these films was found to be strongly dep
endent on the ratio of donors. The ion beam (He+, N+ or Ar+) irradiati
on on these films were also found to increase the conductivity. The mo
st highly conductive films were produced under Nitrogen ion beam irrad
iation.
