Phonons and related crystal properties from density-functional perturbation theory
TL;DR: In this paper, the current status of lattice-dynamical calculations in crystals, using density-functional perturbation theory, with emphasis on the plane-wave pseudopotential method, is reviewed.
Journal ArticleDOI
Structural rigidity and low frequency vibrational modes of long carbon tubules
TL;DR: The “beam bending” mode is found to be one of the softest modes in these structures and the corresponding beam rigity of a “bucky tube” is compared to an found to exceed the highest values found in presently available materials.
Journal ArticleDOI
Impact of size, shape, and composition on piezoelectric effects and electronic properties of In ( Ga ) As ∕ Ga As quantum dots
TL;DR: In this article, a large variety of realistic QD geometries and composition profiles were studied, and the linear and quadratic parts of the piezoelectric field were calculated.

Beyond Pair Potentials in Elemental Transition Metals and Semiconductors
TL;DR: In this paper, the main approaches to transcending pair potential descriptions of transition metals and semiconductors are described. But, to obtain a more sophisticated picture of the transition metals, including structural energy differences, angular forces are necessary, and much of the understanding that has recently been gained of transition metal bonding has also been incorporated in the most recent semiconductor energy functionals.
