Valence band excitations in V_2O_5
S. Atzkern, S. V. Borisenko, M. Knupfer +6
We present a joint theoretical and experimental investigation of the electronic and optical properties of vanadium pentoxide. Electron energy-loss spectroscopy in transmission was…

The size of electron-hole pairs in pi conjugated systems
M. Knupfer, T. Pichler, M. S. Golden +5
We have performed momentum dependent electron energy-loss studies of the electronic excitations in sexithiophene and compared the results to those from parent oligomers. Our experi…

Frenkel and charge transfer excitons in C60
M. Knupfer, J. Fink
We have studied the low energy electronic excitations of C60 using momentum dependent electron energy-loss spectroscopy in transmission. The momentum dependent intensity of the gap…
