Simulation of carrier mobility through Graphene Nanoribbon based DNA sensor

摘要

Graphene Nanoribbons (GNRs), now-a-days, are used in detecting Deoxyribonucleic Acid (DNA) which is one of the breakthroughs in modern nanobiomaterial and biomedical applications. The conductance is calculated by transferring the electron from DNA to Graphene Nanoribbon sample. The conductance is the basic parameter of calculating carrier properties from DNA to GNR pathway. One of the carrier properties is mobility upon which hereditary information can be observed for different patch of helix. In this paper, firstly we will observe conductance for DNA-GNR structure by controlling the gate voltage. Then we will measure the variation of mean free path for different conductance of this structure. From this observation, we will investigate the resistivity and calculate the carrier mobility through DNA to GNR sample.
