Abstract:
Cr2O3:(Mg,N) has been reported as a p-type transparent conducting oxide. In this
contribution the effect of each precursor used for the deposition by spray-pyrolysis,
will be explored and their role in determining the optical and electrical properties of
Cr2O3 will be outlined. A correlation between the structural, electrical, and optical
properties upon introducing nitrogen precursors has been established. In particular it
has been shown that the presence of ammonium salts in the deposition environment
results in less absorbing films. By combining optical measurements and NEXAFS
studies, a mechanism is proposed to explain the change in the optical properties.
Moreover, it is shown that the presence of the nitrate moiety in the reaction
environment is necessary to improve the electrical conductivity of the deposited films.
The reaction of the nitrate moiety with the ammonium moiety has been proposed as
the mechanism to explain the boost in conductivity.
