Hopf insulators and their topologically protected surface states
Hopf insulators topologically protected surface states
2016/1/23
Three-dimensional (3D) topological insulators in general need to be protected by certain kinds of symmetries other than the presumed U(1) charge conservation. A peculiar exception is the Hopf insulato...
The Shockley model description of the surface states in topological insulators
Shockley model description surface states topological insulators
2012/2/27
We show that the surface states in topological insulators can be understood based on a well-known Shockley model, a one-dimensional tight-binding model with two atoms per elementary cell, connected vi...
Surface states on a topologically non-trivial semimetal: The case of Sb(110)
Surface states topologically non-trivial semimetal Sb(110)
2012/2/27
The electronic structure of Sb(110) is studied by angle-resolved photoemission spectroscopy and first-principle calculations, revealing several electronic surface states in the projected bulk band gap...
Scope for New Applications for Gold Arising from the Electrocatalytic Behaviour of its Metastable Surface States
Gold Electrocatalytic
2009/7/28
The electrocatalytic behaviour of gold in aqueous
media is surprisingly complex and a novel view of gold
electrode surfaces is proposed to explain the observed
electrochemical responses. The metal ...

Influence of surface states and bulk traps on non-equilibrium phenomena at GaAs and GaN surfaces
gallium arsenide gallium nitride surface states bulk traps

The influence of surface state density NSS and bulk non-radiative lifetime t on room temperature photoluminescence quantum efficiency YPL and surface photovoltage (SPV) versus the excitation light int...
Sulfur and iron surface states on fractured pyrite surfaces
Sulfur iron surface states pyrite surfaces
2012/4/1
Pyrite has a poor {001} cleavage. Unlike most other minerals with a rocksalt-type structure, pyrite typically fractures conchoidally, demonstrating that parting surfaces are not constrained to the {00...
Analysis of the Charge Transfer in CCDS Including the Effect of Surface States and a Varying Fringing Field
the Charge Transfer CCDS Surface States a Varying Fringing Field
2010/12/14
In this paper, a general charge transfer equation is derived that includes the effect of the surface states and does not assume a constant fringing field. Further, a detailed and simple method is pres...
