FIELD: measuring instrumentation.
SUBSTANCE: ammonia trace contamination sensor includes semiconductor base and substrate. Semiconductor base is made out of polycrystalline cadmium sulphide nanofilm reinforced with cadmium telluride. Electrode pad of pieso-quartz resonator serves as substrate.
EFFECT: significantly simpler design of sensor, several times higher sensitivity than that of existing sensors.
