The rise of 2D materials since the discovery of graphene has been exponential. Their mechanical, electrical and optical properties are exceptional, similar to their 3D counterparts. In this paper, an α − In2Se3 crystal is mechanically exfoliated and transferred directly onto a fiber ferrule to serve...
