To assess the transferability of the trained ANN potential to boundary conditions that were For energy analysis by comparing E f values, except graphene and H-saturated C-chains, there is a slight overestimation with the ANN potential, i.e., the absolute values of the ANN potential's results are smaller than DFT values. However, the trends of stability are successfully captured by the ANN potential. For example, the SWCNT with chirality (8, 0)
