The conditions for fabricating n -FeS_2/ p -Cd_1 –_ x Zn_ x Te heterojunctions by the spray pyrolysis of thin pyrite films on p -Cd_1 –_ x Zn_ x Te crystalline substrates are investigated. A comprehensive analysis of the current–voltage ( I – V ) and capacitance–voltage ( C – V ) characteristics makes it possible to establish the limitation of the reverse current by the space-charge region at small reverse biases and consider the mechanisms of current formation with the participation of energy levels near the heterojunction. A model of the energy profile of the n -FeS_2/ p -Cd_1 –_ x Zn_ x Te heterojunction is proposed, which turns out to be in good correspondence with the experimentally determined parameters and the dynamics of their change with a variation in temperature.
