Patent ID: 6981727

Claim:
Diode-type nanotweezers comprising a first arm and a second arm that are formed so as to project from a holder and are freely opened and closed by an electrostatic force applied between tip end portions of said first and second arms so as to hold a nanosubstance, wherein said first arm is formed by a gate nanotube which is fastened at a base end portion thereof to said holder and a tip end portion thereof protrudes from said holder, said second arm is formed by a nanotube diode which is fastened at two base end portions thereof to said holder and has a diode characteristic portion at a tin end nortion thereof, and said nanotube diode is formed by folding one nanotube into two nanotube fragments so that both ends thereof are fastened, as said base end portions, to said holder and a tip end thereof which is a folded portion thereof forms said diode characteristic portion that has diode characteristics.
