Abstract
This paper describes an application of carbon-type semiconductors for the construction of humidity-sensitive diodes. The sensing diodes consist of two semiconducting layers with different electronic properties deposited onto a quartz substrate by means of the spray pyrolysis method. The main electronic properties of carbons, i.e., electrical conductivity, and the type of majority current carriers were estimated by a suitable heat treatment. This resulted in the construction of humidity-sensitive diodes exhibiting a typical voltage-current diode-like behaviour in the presence of moisture. Some water adsorption and electronic properties of single carbon layers are also presented and discussed in terms of the amplification effect of the diode junction.
