The influence of thermal treatment on the adhesion of thin gold films on Al 2 O 3 ceramic substrates has been investigated by scratch test measurements. The adhesion was found to be substantially increased when the systems were heat-treated at 500 o C, and the adherence depends on the length of treatment. An attempt to explain the improved adhesion was made by using X-ray photoelectron...
We have studied the influence of plasma and thermal treatments on the electrical properties of poly(para-phenylene vinylene) (PPV) thin films in metal-polymer-metal structures. Thermal heating of the samples modifies the diode characteristic by reducing the voltage threshold and by favouring the formation of the rectifying contact at the bottom side. Plasma treatments with oxygen or nitrogen drastically...
