Resonant versus anti-resonant tunneling at carbon nanotube A-B-A heterostructures
N. Mingo, Liu Yang, Jie Han +1
Narrow antiresonances going to zero transmission are found to occur for general (2n,0)(n,n)(2n,0) carbon nanotube heterostructures, whereas the complementary configuration, (n,n)(2…
Transmission Through Carbon Nanotubes With Polyhedral Caps
M. P. Anantram, T. R. Govindan
We study electron transport between capped carbon nanotubes and a substrate, and relate the transmission probability to the local density of states in the cap. Our results show tha…
Charging effects in the ac conductance of a double barrier resonant tunneling structure
M. P. Anantram
There have been many studies of the linear response ac conductance of a double barrier resonant tunneling structure (DBRTS). While these studies are important, they fail to self-co…
Metastable states and information propagation in a 1D array of locally-coupled bistable cells
M. P. Anantram, Vwani P. Roychowdhury
We study the effect of metastable states on the relaxation process (and hence information propagation) in locally coupled and boundary-driven structures. We first give a general ar…
Bandgap Change of Carbon Nanotubes: Effect of Small Tensile and Torsional Strain
Liu Yang, M. P. Anantram, Jie Han +1
We use a simple picture based on the electron approximation to study the bandgap variation of carbon nanotubes with uniaxial and torsional strain. We find (i) that the magnitud…
Conductance of carbon nanotubes with disorder: A numerical study
M. P. Anantram, T. R. Govindan
We study the conductance of carbon nanotube wires in the presence of disorder, in the limit of phase coherent transport. For this purpose, we have developed a simple numerical proc…
