Paradoxical Magnetic Cooling in a Structural Transition Model
Peter Borrmann, Heinrich Stamerjohanns, Eberhard R. Hilf +1
In contrast to the experimentally widely used isentropic demagnetization process for cooling to ultra-low temperatures we examine a particular classical model system that does not…
Photogalvanic Effects in Heteropolar Nanotubes
P. Kral, E. J. Mele, D. Tomanek
We show that an electrical shift current is generated when electrons are photoexcited from the valence to conduction bands on a BN nanotube. This photocurrent follows the light pul…
Electronic and Structural Properties of Carbon Nano-Horns
Savas Berber, Young-Kyun Kwon, David Tomanek
We use parametrized linear combination of atomic orbitals calculations to determine the stability, optimum geometry and electronic properties of nanometer-sized capped graphitic co…
Unusually High Thermal Conductivity of Carbon Nanotubes
Savas Berber, Young-Kyun Kwon, David Tomanek
Combining equilibrium and non-equilibrium molecular dynamics simulations with accurate carbon potentials, we determine the thermal conductivity of carbon nanotubes and its depe…
