| dc.description.abstract | This project is devoted to the investigation of the modern state of the problem connected with quantum Hall effect (integral and fractional). The quantum Hall effect is a quantum-mechanical version of the Hall effect, observed in two dimensional electron systems subjected to low temperatures (< 11) and strong magnetic fields (∼ 104), in which the Hall conductance5( ) takes on the quantized values(678 9 ) with : an integer (integer quantized Hall effect) or a rational fraction (fractional quantized Hall effect), independent of the detail of the sample geometry. in this project we see detail description of fractional quantum hall effect by using some theories, It starts from the LAUGHLIN states and their generalization following JAIN’s picture of composite fermions. The work of this project ends with a description of the fractional quantum hall effect in graphene, since graphene is two dimensional carbon and carbon atoms in graphene, shows electron-electron interaction thus we must expect fractional quantum hall effect in graphene | en_US |
