Abstract We analyze the graphane p-n junction performance. The analysis method is based on solving Poisson and current equations by using the Green function method. The Green function method gives a simple and fast tool for solving the Poisson equation. Our analysis method is different compared to earlier reports about the analysis of the graphane p-n junction. By using the presented method, the electrical field, electrical potential, and carrier concentration in devices are calculated. Our results are in agreement with numerical and experimental results reported by other researchers. Due to taking into account the carrier concentration in the space charge region, the precision of our results is better than former ones.
