Abstract
Bilayer structure with copper phthalocyanine (CuPc~100 nm)
and palladium (~18 nm), has been studied for hydrogen
gas-sensing application at
C and
C temperatures. The structure was fabricated in a two different
vacuum deposition processes (first the CuPc film and than the Pd)
onto a LiNbO3 Y- cut Z-propagating substrate for a SAW method
and additionally (in this same technological processes) onto a glass
substrate with a planar microelectrode array for simultaneously
monitoring of the structure planar resistance. A good correlation
has been observed between this two methods - frequency changes for
SAW method coincide with decreasing of the bilayer structure
resistance. Although the simultaneously measurements not always were
possible (too big resistance of the sample) they can give
informations about the acoustoelectric interactions between SAW and
charge carriers in the bi-layer structure.
