Plasmon electron-hole resonance in epitaxial graphene
C. Tegenkamp, H. Pfnuer, T. Langer +2
The quasiparticle dynamics of the sheet plasmons in epitaxially grown graphene layers on SiC(0001) have been studied systematically as a function of temperature, intrinsic defects,…
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…
