Graphene to Graphane and its effect on band gap

Nallin Sharma, Madhuri Sharon, Bhushan Patil, Maheshwar Sharon

Abstract :

 Studies were made to convert graphene (a zero band gap semiconductor material) to Graphane, a non-zero band gap material. Band gap was determined by Tauc plotting. It was observed that graphane possess both indirect band gap (1.26, 1.37 and 1.68eV) and direct band gap (4.0, 415 and 5.25 eV). The magnitude of these band gaps can be controlled by hydrogenation. It was found that band gap of graphene (C=C carbon) increased to higher value by controlled conversion of C=C to C-C carbon. Graphane was characterised by Raman spectroscopy and UV-Vis spectroscopy
