摘要：

We have investigated the stabilities of boron nitride nanoribbons with different hydrogen-terminated edges by first principles calculations. Five kinds of the stable edges are determined for the zigzag boron nitride nanoribbons (ZBNNRs). While for the armchair boron nitride nanoribbons (ABNNRs), there are three kinds of the stable edges. ZBNNRs under hydrogen rich environment are found to be ferromagnetic metals, while ABNNRs are nonmagnetic semiconductors regardless of the hydrogen content.
