Enhanced Optical Conductivity Induced by Surface States in ABC-stacked Few-Layer Graphene
Jia-An Yan, W. Y. Ruan, M. Y. Chou
The surface states of ABC-stacked few-layer graphene (FLG) are studied based on density-functional theory. These states form flat bands near the Fermi level, with the k-space range…
Structural and Electronic Properties of Oxidized Graphene
Jia-An Yan, Lede Xian, M. Y. Chou
We have systematically investigated the effect of oxidation on the structural and electronic properties of graphene based on first-principles calculations. Energetically favorable…
A 2MASS All-Sky View of the Sagittarius Dwarf Galaxy: Variation of the Metallicity Distribution Function Along the Sagittarius Stream
Mei-Yin Chou, Steven R. Majewski, Katia Cunha +9
We present reliable measurements of the metallicity distribution function (MDF) at different points along the tidal stream of the Sagittarius (Sgr) dwarf spheroidal (dSph) galaxy,…
Beyond the local approximation to exchange and correlation: the role of the Laplacian of the density in the energy density of Si
Antonio C. Cancio, M. Y. Chou
We model the exchange-correlation (XC) energy density of the Si crystal and atom as calculated by variational Monte Carlo (VMC) methods with a gradient analysis beyond the local de…
Exploring Halo Substructure with Giant Stars: The Velocity Dispersion Profiles of the Ursa Minor and Draco Dwarf Spheroidals At Large Angular Separations
Ricardo R. Munoz, Peter M. Frinchaboy, Steven R. Majewski +6
We analyze velocity dispersion profiles for the Draco and Ursa Minor (UMi) dwarf spheroidal (dSph) galaxies based on published and new Keck HIRES spectra for stars in the outer UMi…
