| Summary: | The carrier mobility in low-field specifically in parabolic energy region of one-dimensional graphene nanoribbon (GNR) band energy is presented in this work. Low-field mobility model describe the carrier transport and its dependency factors when dealing with degenerate and non-degenerate principals. The result shows that the low-field mobility strongly depends on the temperature in the non-degenerate regime in which it sharply decreases with increasing temperature in the range of 10–250 K but the mobility is less affected by the temperature above 250 K. The effect of varying the GNR width to the mobility is also demonstrated in this work. In addition, it is also shown that the mobility depends on the carrier concentration in degenerate domain in which it increases at higher carrier concentrations. |
