RESISTIVE MATERIAL BASED ON NON-STOICHIOMETRIC SULPHIDES Russian patent published in 2017 - IPC H01C7/00 

FIELD: electronics.

SUBSTANCE: invention relates to radio- and microelectronics and can be used in microelectronic equipment with low values of currents and voltages, which requires switching within time intervals from 25 to 110 minutes at 10–150 °C. Resistive material contains silver sulphide, non-stoichiometric germanium sulphide and non-stoichiometric arsenic sulphide according to empirical formula: 0.5(Ag₂S)⋅(Ge_1+xS)⋅0.5(As_2-2xS₃), where 0.4≤x≤0.8.

EFFECT: material shows declared properties: functional dependence of resistance on the application time of constant difference in potentials, has time periods of electric conductivity relaxation from 70 to 196 seconds and the value of specific electrical resistance of about 10⁵–10⁶ Ohm⋅m, within temperature range of 10–150 °C.
