Abstract

Diamond is a popular material, not only as a gem but also for basic and applied research owing to its extraordinary properties. The discovery of superconductivity in heavily doped diamond has increased its importance. Although the highest superconducting critical temperature (T_c) is 10K, it is regarded as a superconductor with a potentially high T_c, owing to the strong covalent bonding between carbon atoms and the light atomic mass of carbon. In this chapter, after reviewing the fundamentals of the electronic states of pristine and doped diamond, we describe the electronic states, together with the vibrational properties, of borondoped superconductive diamond, which have been revealed by photoemission spectroscopy and other experimental techniques.
