METHOD TO CONTROL CURRENT AND DEVICE FOR ITS REALISATION Russian patent published in 2014 - IPC H01L29/80 

FIELD: electricity.

SUBSTANCE: control of current value in an instrument with a vertical structure comprising a conducting area with n-type of conductivity (n-area), an anode, which is located on the lower side of the n-area, a control electrode formed on the upper side of the n-area and forming a Schottky barrier with it, and a cathode arranged on the side surface of the n-area between the anode and the control electrode, is carried out by variation of the area and accordingly resistance of the ohmic contact between the cathode and the n-area. The instrument may contain more than one unit structure, at the same time adjacent unit structures are combined into a new structure with two cathodes, a single n-area with an anode and a control electrode.

EFFECT: invention makes it possible to increase efficiency and current and output capacity of an instrument.
