M. Takenaga et al., HALL-COEFFICIENT MEASUREMENT OF PYROLYTIC POLYIMIDE FILM PREPARED USING LANGMUIR-BLODGETT METHOD, JPN J A P 1, 33(10), 1994, pp. 5848-5849
Hall effect measurements of pyrolytic Langmuir-Blodgett films based on
a biphenyl-type polyimide have been done using a double frequency met
hod. The Hall coefficient had a negative sign over the measuring tempe
rature range; an electron density of 10(21) cm(-3) and a Hall mobility
of around 0.5 cm(2) (Vs)(-1) could be estimated on the assumption of
a one-carrier conduction. The Hall mobility is characterized by a sing
le activated process with 5.4 meV.
