Formation of Surface and Quantum-Well States in Ultra Thin Pt Films on the Au(111) Surface
(MDPI, 2017-12-09)
The electronic structure of the Pt/Au(111) heterostructures with a number of Pt monolayers n ranging from one to three is studied in the density-functional-theory framework. The calculations demonstrate that the deposition ...
New generation of two-dimensional spintronic systems realized by coupling of Rashba and Dirac fermions
(Nature Publishing Group, 2015-08-04)
Intriguing phenomena and novel physics predicted for two-dimensional (2D) systems formed by electrons in Dirac or Rashba states motivate an active search for new materials or combinations of the already revealed ones. Being ...
Hole-Phonon Relaxation and Photocatalytic Properties of Titanium Dioxide and Zinc Oxide: First-Principles Approach
(Hindawi Publishing, 2014)
First-principles calculations for the temporal characteristics of hole-phonon relaxation in the valence band of titanium dioxide and zinc oxide have been performed. A first-principles method for the calculations of the ...
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 ...
Time-dependent electron phenomena at surfaces
(US National Academy of Sciences, 2011-01)
Femtosecond and subfemtosecond time scales typically rule electron dynamics at metal surfaces. Recent advance in experimental techniques permits now remarkable precision in the description of these processes. In particular, ...
Spin-helical Dirac states in graphene induced by polar-substrate surfaces with giant spin-orbit interaction: a new platform for spintronics
(Nature Publishing Group, 2014-11-04)
Spintronics, or spin electronics, is aimed at efficient control and manipulation of spin degrees of freedom in electron systems. To comply with demands of nowaday spintronics, the studies of electron systems hosting giant ...
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 ...
