Specifikacia Nanostructured Carbon Electron Emitters and Their Applications
Carbon forms a variety of allotropes (structures) due to the diverse hybridization of s- and p-electron orbitals, time-honored graphite (two dimensional structure) and diamond (three dimensional network), new forms such as C60 fullerene (cage structure), nanotube (quasi-one dimensional structure), graphene (truly two dimensional network), and carbyne (truly one dimensional chain). The family of new allotropes (fullerene, nanotube, graphene, carbyne) are called "nanostructured carbon" or "nanocarbon". They exhibit extreme properties, e.g., ultrahigh mechanical strength, ultrahigh charge carrier mobility, high thermal conductivity and so on, thus attracting considerable attentions for electronic and mechanical applications as well as in basic materials science for exploring new physics and chemistry.Carbon nanotube (CNT) and graphene possess excellent properties as
