Originální abstrakt

Thick conducting films based on carbon/graphite particles in polymer vehicle are characterised by noise measurements. The samples structure consists of conducting particles and inter-particle layers with semiconductor conductivity. The sources of fluctuations are both in the conducting particles volume and in contact region between carbon/graphite particles. The low frequency noise spectral density is 1/fa type and it is proportional to the square of the current, voltage or electric field intensity. The frequency factor a is very near to 1. We suppose, that there is a fundamental 1/f noise component as a result of mobility fluctuation. Additional is excess 1/f noise component generated at the interfaces between conducting particles and polymer vehicle. The main problem is if 1/f fluctuation is caused by fluctuation of a number of carriers acting in transport or by mobility fluctuation due to scattering process.
