PDOS of CNT(5, 5) and BNNT(10, 10) under an external electric field of (a) V/Å and (b) V/Å, respectively. PDOS of CNT(5, 5)@BNNT(10, 10) under an external electric field of (c) V/Å and (d) V/Å, respectively. The Fermi level lies at 0 eV (dotted line). The solid line corresponds to p-state of C, B, and N at pristine CNT(5, 5) and BNNT(10, 10), respectively.
