Abstract :
Using the quantum tunneling theory with the tight-binding approach, we study the effects of Peierls distortion and the magnetic field in the field emission of carbon nanotubes. The Peierls distortion opens an energy gap at Fermi level, which suppresses the emission current. The responses of the emission current to the magnetic field are quite different for the semiconducting and metallic tubes
