Abstract

Abstract: The thickness of a monolayer graphene is extremely thin, ≈0.34 nm, so exact measurement of the optical path length and optical path length difference of graphene is challenging. This paper uses white‐light interferometry and a horizontal grating to obtain the optical characteristic curve of graphene. Then, the real existence of vacuum channels (VCs) in monolayer graphene is discovered. These VCs naturally eliminate the collision phenomena, and provide zero electrical resistance and superconductivity (SC) states. Multiple SC states (SCSs), SC persistence, magnetic field response, VCs transmitting a SC current with high efficiency, screen characteristics of VCs, etc. are discussed. Experiments show that only when a graphene ribbon is located at the exact position of the VC, does it transmit the SC current and provide a SCS. The duration of the persistence tests is 2 months. All experiments are conducted in a completely open space of a laboratory. Graphene SC at room‐temperatures of a wide range and standard atmosphere is achieved. This paper uses the optical technology to realize graphene SC, points out the basic reason of realizing it, and provides the experimental evidences. Abstract : Superconductivity (SC) always exists under the condition of helium liquefaction temperature or nitrogen liquefaction temperature. This paper uses optical technology to realize graphene SC at room‐temperature of a wide range and standard atmosphere based vacuum channels (VCs) and white‐light interferometry. The graphene ribbon should be located at the correct position of VC.
