Preliminary diagnosis of human diseases such as cancer and diabetes is possible via the detection of violate organic compounds (VOCs) contained in exhaled breath gases. A pre-threshold electron emission yield from a solid emitter depends on the gas molecules adhered to the emitter, if the electron work function is influenced. The paper demonstrates that pre-threshold electron emission from a silicon solid emitter could be employed to detect exhaled VOCs.
