Graphene and its Phononics: A Review

Graphene, a unique allotrope of carbon, has garnered a huge amount of attention amongst researchers as its unique properties and promising applications in various real-life domains like in efficient batteries, solar cells, medicinal technologies, environmental remediation, circuit boards, lighting and display, and anti-corrosion has resulted in its commercial exploitation and implementation in everyday life. Since 2004 graphene has been one of the most beautiful scientific and technological achievements. The unique electronic cloud forming the bond between different carbon atoms in graphene leads to several inquisitive questions raised in the field of quantum physics. Till now graphene has been exploited for its electronic and optical properties but new research has shown that phononic properties of graphene will lead to the development of “killer” practical applications in the future. In this review article we have explored the structure, properties and the phononics of graphene with a special reference to few-layer graphene (FLG) and graphene Thermal Interface Materials (TIMs).
