Doping Dependence of Gap Inhomogeneities at BiSrCaCuO Surfaces
Wei Chen, Marc Gabay, Peter J Hirschfeld
We study the inhomogeneity of the electronic pairing gap observed by STM near the surface of BiSrCaCuO to be correlated with interstitial O defects. We tr…
Organic Molecules on Wide-Gap Insulators: Electronic Excitations
Wei Chen, Christoph Tegenkamp, Herbert Pfnür
The electronic excitation of a conjugated molecule-insulator interface, as exemplified by the adsorption of benzoic acid and its phenolic derivative on NaCl(001) surface, is addres…
Color centers in NaCl by hybrid functionals
Wei Chen, Christoph Tegenkamp, Herbert Pfnür +1
We present in this work the electronic structure and transition energies (both thermodynamic and optical) of Cl vacancies in NaCl by hybrid density functionals. The underestimated…
Anomalous molecular orbital variation upon adsorption on wide band gap insulator
Wei Chen, Christoph Tegenkamp, Herbert Pfnür +1
It is commonly believed that organic molecules are physisorbed on the ideal non-polar surfaces of wide band gap insulators with limited variation of the electronic properties of th…
Metal-insulator transition in vanadium dioxide nanobeams: probing sub-domain properties of strongly correlated materials
Jiang Wei, Zenghui Wang, Wei Chen +1
Many strongly correlated electronic materials, including high-temperature superconductors, colossal magnetoresistance and metal-insulator-transition (MIT) materials, are inhomogene…
