Abstract: PURPOSE:To enable to operate bistable oscillation in a high frequency with negative resistance in a simple circuit by providing a vertical negative resistor in an applied reverse high electric field by avalanche phenomenon in a semiconductor P-N junction. CONSTITUTION:Silicon semiconductor P-N junction surfaces are planely bonded, a negative resistor is provided between two parallel electrodes 4 and 5 provided in a P type semiconductor section, an electrode 6 is further provided to effectively produce the negative resistance.
