Description

Recently organic semiconductors have obtained
considerable interest in the fields of electronic
and photonic devices due to a wide range of
applications and low cost. This work describes
fabrication and investigations of organic
semiconductor devices such as humidity, light and
temperature sensors based on copper phthalocyanine
(CuPc). Temperature dependent properties of organic-
inorganic (Ag/CuPc/GaAs/Ag) heterojunctions were
investigated in a wide temperature range of 82 to
350 K. The fabricated junctions could be used as
photo-electric sensors for the NIR-UV spectral
region. A photoelectric displacement transducer,
organic phototransistor based on CuPc, and photo
capacitive sensor based on poly-N-
epoxypropylcarbazole complexes were fabricated and
investigated as well. The concept of multi-
functional sensors using organic semiconductors is
discussed. Properties of CuPc films deposited at
high gravity conditions from 50g to -50g by
centrifugation were investigated.
