Abstract
The present work has simulated the piezoresistivity coefficient in graphene ribbon based on the first-principles electronic-state calculation method. The carrier conductivity along the graphene ribbon models have been calculated using band carrier densities and their corresponding effective masses derived from the one-dimensional band diagram. The longitudinal and transverse gauge factors are large in our calculation, and the zigzag graphene ribbon is a high potential material with high piezoresistivity.
