Abstract: Integrated Circuits form the backbone of all electronic and Computation Systems. Their working is based on the typical properties of semiconductor materials. Presently Silicon is ruling semiconductor but it will not be handle further miniaturization of devices and circuits. Carbon is focus of research for use in nanoelectronics. Carbon belongs to same group as that of Silicon and Germanium in periodic table. This motivation leads to study of various carbon allotropes that may have ability to sustain Moore’s law. In this paper a review has been done of various carbon allotropes and techniques to analyze them.

Keywords: Allotropes, Carbon, Nanoelectronics, Spectroscopy.
