Variable and reversible quantum structures on a single carbon nanotube
C. Kilic, S. Ciraci, O. Gulseren +1
The band gap of a semiconducting single wall carbon nanotube decreases and eventually vanishes leading to metalization as a result of increasing radial deformation. This sets in a…
Soft Phonon Anomalies in Relaxor Ferroelectrics
G. Shirane, P. M. Gehring
A review is given of the phonon anomalies, which have been termed ``waterfalls,'' that were recently discovered through a series of neutron inelastic scattering measurements on the…
Dynamical effects of the nanometer-sized polarized domains in Pb(Zn1/3Nb2/3)O3
P. M. Gehring, S. -E. Park, G. Shirane
Recent neutron scattering measurements performed on the relaxor ferroelectric Pb[(Zn1/3Nb2/3)0.92Ti0.08]O3 (PZN-8%PT) in its cubic phase at 500 K, have revealed an anomalous ridge…
Pressure-Induced Interlinking of Carbon Nanotubes
T. Yildirim, O. Gulseren, C. Kilic +1
We predict new forms of carbon consisting of one and two dimensional networks of interlinked single wall carbon nanotubes, some of which are energetically more stable than van der…
Thermal Equation of State of Tantalum
Ronald E. Cohen, O. Gulseren
We have investigated the thermal equation of state of tantalum from first principles using the Linearized Augmented Plane Wave (LAPW) and pseudopotential methods for pressures up t…
Soft Mode Anomalies in the Perovskite Relaxor Pb(Mg1/3Nb2/3)O3
P. M. Gehring, S. B. Vakhrushev, G. Shirane
Neutron inelastic scattering measurements of the polar TO phonon mode in the cubic relaxor Pb(Mg1/3Nb2/3)O3, at room temperature, reveal anomalous behavior similar to that recently…
