The direct and alternating current conductivity, space
charge limited current, and TEP properties of boron-containing
poly(vinyl alcohol)-derived ceramic obtained at
973 K have been investigated. The electrical conductivity
and thermoelectric power measurements suggest that the
PVAB sample behaves as a p-type organic semiconductor.
The current–voltage measurements indicate that the space
charge limited conduction is dominant in the PVAB sample.
Alternating current conductivity results that the CBH
conductivity is dominant in AC conductivity mechanism
of the sample. A temperature-dependent non-Debye relaxation
is dominant in the PVAB sample.
