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...
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 ...

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...
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...
