Theoretical study on transport properties of a BN co-doped SiC nanotube

► BN co-doping suppresses the negative differential resistance property of SiCNT. ► HOMO has no contribution from BN impurity. ► LUMO is contributed from nitrogen atoms at low and high bias voltages. ► BN co-doping results in exponential increase in current with bias. ► Rectification is negligible.
