Ring crystalline body and production method thereof

Abstract

To provide a ring crystalline body, which is a ring crystalline body with a small diameter and formed with a thin line and capable of providing electric conduction along the ring, and to provide a production method of the ring crystalline body. A droplet is stuck to a surface of a substrate and then the droplet is evaporated to a discontinuous underlayer ring having an ultrafine three-dimensional structure on the substrate surface. After that, when a transition metal dichalcogenide, a transition metal trichalcogenide, or a low-dimensional conductor as raw material gas is evaporated, a ring crystalline body comprising the raw material is grown along the underlayer ring.
