ABSTRACT:
An electronic device is presented for performing at least one logic function. The device comprises an electron emission based electrode arrangement associated with an electron extractor. The electrode arrangement comprises at least one basic unit including a photocathode, an anode, and one or more gates arranged aside a cavity defined between the photocathode and the anode. Said one or more gates are connectable to a voltage supply unit to be operated by one or more input voltages signals corresponding to one or more logical values, respectively. Said anode is operable as a floating electrode from which an electrical output of the device indicative of a resulted logic function is read. The anode is electrically connected to a photocathode of another cathode-anode unit of the same device, or is connected to an electrode of another electronic device.
