Excitonic Effects on the Optical Response of Graphene and Bilayer Graphene
Li Yang, Jack Deslippe, Cheol-Hwan Park +2
We present first-principles calculations of many-electron effects on the optical response of graphene, bilayer graphene, and graphite employing the GW-Bethe Salpeter equation appro…
First-Principles Study of Electron Linewidths in Graphene
Cheol-Hwan Park, Feliciano Giustino, Catalin D. Spataru +2
We present first-principles calculations of the linewidths of low-energy quasiparticles in n-doped graphene arising from both the electron-electron and the electron-phonon interact…
Calcium-Decorated Carbon Nanotubes for High-Capacity Hydrogen Storage
Hoonkyung Lee, Jisoon Ihm, Marvin L. Cohen +1
Using first-principles calculations, we perform a search for high-capacity hydrogen storage media based on individually dispersed calcium atoms on doped or defective carbon nanotub…
