Most DFT practitioners use regular grids (Monkhorst-Pack, MP) for integrations in the Brillioun zone. Although regular grids are the natural choice and easy to generate, more general grids whose generating vectors are not merely integer divisions of

Indium-doped CdSe nanoparticles have been synthesized and characterized. Their light absorption, photoluminescence, and structure are similar to undoped CdSe nanoparticles. The greater part of the In associated with the nanoparticles is removed when

CdSe nanocrystals in solution and films can enter a metastable state in which the highly luminescent nanocrystals become dark. This change, which we attribute to a surface transformation, can be caused by heating or by changing the environment of the

Photoinduced polymerization and photoinduced diffusion of molecular oxygen in thin C60 films irradiated by femtosecond laser pulses are investigated. A comparison of the Raman scattering and absorbed energy spectra and the irradiation doses required

We have studied electroabsorption (EA) in both films and disperssed molecules of C 60 and C 70 . In contrast to a recent model for the third harmonic generation (THG) spectrum, we find that the two-photon states important to the nonresonant χ (3) (0

This systematic study of transition metal (TM) substitution for H on graphane TM x H1-x C, (TM = Sc, Ti, V, Cr, Mn) combines ab initio calculations and cluster expansion to explore a huge variety of structures in more than 20 supercells over the full

We have studied the singlet exciton decay by picosecond photoinduced absorption in films of C[sub 60], under pressures up to 62 kbar. The picosecond decay of excitons excited in the absorption tail continues to be dominated by broad distributions of

We calculate the spatial distribution of the oscillating electron density for the low energy optical excitations in C(60), using ab initio time-dependent density functional theory. We contrast this with the unscreened free response of the Kohn-Sham e
