Abstract: I will speak briefly about the discovery of carbon nanotubes (CNT) with emphasis on importance of modern electron microscopy [1]. Many unique properties of CNT, its basic structure being graphene of a hexagonal network of carbon atoms, come from their cylindrical form and nanometer sized diameter as well as hybridized electron orbitals of a carbon atom. The CNTs having flexible and unique electronic properties have been successfully commercialized as touch-panel devices. Some new developments in photo-thermal conversions are discussed.

Modern electron optical technology including high resolution microscopy, electron energy loss spectroscopy (EELS) [3] and energy dispersive X-ray analysis (EDX) [4] has progressed greatly and supported widely innovative research on nano-materials. Some of typical examples of atomic detailed characterizations of CNTs, graphene sheets and related nano-materials will be presented.
