First-principles calculations of hot-electron lifetimes in metals
(American Physical Society, 2000)
First-principles calculations' of the inelastic lifetime of low-energy electrons in Al, Mg, Be, and Cu are reported. Quasiparticle damping rates are evaluated from the: knowledge of the electron self-energy, which we compute ...
Role of occupied d bands in the dynamics of excited electrons and holes in Ag
(American Physical Society, 2003)
The role that occupied d bands play in the inelastic lifetime of bulk and surface states in Ag is investigated from the knowledge of the quasiparticle self-energy. In the case of bulk electrons, sp bands are taken to be ...
Energy loss of charged particles moving parallel to a magnesium surface
(American Physical Society, 2008-10)
We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical ...
Ab initio calculation of low-energy collective charge-density excitations in MgB2
(American Physical Society, 2009-08)
We present ab initio time-dependent density-functional theory calculation results for low-energy collective electron excitations in MgB2. The existence of a long-lived collective excitation corresponding to coherent charge ...
Role of occupied d states in the relaxation of hot electrons in Au
(American Physical Society, 2000-07-15)
We present first-principles calculations of electron-electron scattering rates of low-energy electrons in Au. Our full band-structure calculations indicate that a major contribution from occupied d states participating in ...
Thin Magnetically Soft Wires for Magnetic Microsensors
Recent advances in technology involving magnetic materials require development of novel advanced magnetic materials with improved magnetic and magneto-transport properties and with reduced dimensionality. Therefore magnetic ...
