Quantum Interference Effects in Electronic Transport through Nanotube Contacts
Calin Buia, Alper Buldum, Jian Ping Lu
Quantum interference has dramatic effects on electronic transport through nanotube contacts. In optimal configuration the intertube conductance can approach that of a perfect nanot…
Gas molecule adsorption in carbon nanotubes and nanotube bundles
Jijun Zhao, Alper Buldum, Jie Han +1
We studied various gas molecules (NO, O, NH, N, CO, CH, HO, H, Ar) on single-walled carbon nanotubes (SWNTs) and bundles using first principles meth…
Structure of aluminum atomic chains
Prasenjit Sen, S. Ciraci, A. Buldum +1
First-principles density functional calculations reveal that aluminum can form planar chains in zigzag and ladder structures. The most stable one has equilateral triangular geometr…
Contact resistance between carbon nanotubes
Alper Buldum, Jian Ping Lu
Quantum transport properties of intermolecular nanotube contacts are investigated. We find that atomic structure in the contact region plays important roles and resistance of conta…
Observation of Nanometer-Scale Rolling Motion Mediated by Commensurate Contact
M. R. Falvo, J. Steele, A. Buldum +5
We report, through experimental observations and computer simulations, that atomic lattice interlocking can determine whether an object rolls or slides on a surface. We have quanti…
First principles study of Li intercalated carbon nanotube ropes
Jijun Zhao, Alper Buldum, Jie Han +1
We studied Li intercalated carbon nanotube ropes by using first principles methods. Our results show charge transfer between Li and C and small structural deformation of nanotube d…
Quantum heat transfer through an atomic wire
A. Buldum, S. Ciraci, C. Y. Fong
We studied the phononic heat transfer through an atomic dielectric wire with both infinite and finite lengths by using a model Hamiltonian approach. At low temperature under ballis…
The structural and electronic properties of germanium clathrates
Jijun Zhao, Alper Buldum, Jianping Lu +1
The structural and electronic properties of germanium clathrates Ge and KGe are studied by first principles calculations within the local density approximation. T…
Atomic Scale Sliding and Rolling of Carbon Nanotubes
A. Buldum, Jian Ping Lu
A carbon nanotube is an ideal object for understanding the atomic scale aspects of interface interaction and friction. Using molecular statics and dynamics methods different types…
