Provided is a logical operation element that performs logical operations on three or more inputs using a single unique device. The logical operation elementis provided with an electrodeA and the other electrodeB that are provided to have a nanogap, a metal nanoparticlearranged between the electrodeA and the other electrodeB in insulated state, and a plurality of gate electrodesC,D,A,B for adjusting a charge of the metal nanoparticle. Electric current that flows between the electrodeA and the other electrodeB is controlled in accordance with the voltage applied to three or more of the gate electrodesC,D,A,B.

Logical operation element

This invention is to provide a nanodevice, which is combined with an electronic device such as a diode, tunnel device and MOS transistor, integrated circuit and manufacturing method of the nanodevice. A nanodevice includes: a first insulating layer; one electrodeA and the other electrodeB provided to have a nanogap on the first insulating layer; a metal nanoparticle or a functional molecule provided between the one electrodeA and the other electrodeB; a second insulating layerprovided on the first insulating layer, and on the one electrodeA and the other electrodeB to embed the metal nanoparticle or the functional molecule. The second insulating layer works as a passivating layer.

Nanodevice and method for fabricating the same

A method for controlling a structure of a nano-scale substance, which comprises irradiating a mixture of low-dimensional quantum structures having a nano-scale with an electromagnetic wave in an oxygen atmosphere, to thereby selectively oxidize a low-dimensional quantum structure having a density of states resonating with the electromagnetic wave used for the irradiation. The method allows a low-dimensional quantum structure having a specific structure to be selectively disappeared from the mixture of low-dimensional quantum structures having a nano-scale.
