A. Assadi et al., FABRICATION AND CHARACTERIZATION OF SCHOTTKY GATE POLY(3-ALKYLTHIOPHENE) PLANAR FIELD-EFFECT TRANSISTORS, Synthetic metals, 58(2), 1993, pp. 187-193
In this paper fabrication and characterization of Schottky gate planar
field-effect transistors using poly(3-alkylthiophene) as an active se
miconductor region are reported. This is the first time that planar ME
SFET transistors utilizing a polymer semiconductor have been fabricate
d and measured. Aluminium metal is used for the rectifying contact and
two gold electrodes are constructed as source and drain. From the MES
FET characteristic the channel carrier mobility is evaluated as 10(-5)
cm2 V-1 s-1, which is one order of magnitude larger than a MOSFET uti
lizing the same polymer.
