We demonstrate that the electron density of the light-populated image potential states in graphite reaches its maximum when the photon energy of ultrashort laser pulses is resonant …

We show that when the graphene planes of graphite are uniformly expanded, thereby increasing the C C bond length to 1.7 Å, the σ* edge onset of the energy-loss near-edge …
Time dynamics of photoexcited electron-hole pairs is important for a number of technologies, in particular solar cells. We combined ultrafast pump-probe Raman scattering and …

Photoinduced structural phase transition (PSPT) s are reviewed in connection with recent experimental results. There are two key concepts: the hidden multi-stability of the ground …

Ultra-thin graphite overlayers prepared by heating SiC crystals can give highly resolved valence band photoemission spectra. This is exploited to monitor K deposition induced …

Multiphoton photoemission spectroscopy of graphite using 267 nm (4.65 eV) and 400 nm (3.1 eV) excitation wavelength reveals spectroscopic features that allow the identification of …
Core-level photoemission spectra of graphite have been measured at very high resolution. The C 1 s level is found to have a lifetime width with an upper limit of 165±15 meV, which is …
Here we revisited the electronic structure of potassium doped graphite using angle‐resolved photoemission spectroscopy (ARPES). We perform an analysis of the charge transfer from …
