Exciton properties of selected aromatic hydrocarbon systems
Friedrich Roth, Benjamin Mahns, Silke Hampel +4
We have examined the singlet excitons in two representatives of acene-type (tetracene and pentacene) and phenacene-type (chrysene and picene) molecular crystals, respectively, usin…
Electronic excitations of potassium intercalated manganese phthalocyanine investigated by electron energy-loss spectroscopy
Benjamin Mahns, Friedrich Roth, Mandy Grobosch +2
The electronic excitations of manganese phthalocyanine (MnPc) films were studied as a function of potassium doping using electron energy-loss spectroscopy in transmission. Our data…
Exciton character in picene molecular solids
Friedrich Roth, Benjamin Mahns, Bernd Büchner +1
We have studied the low-energy electronic excitations of solid picene at 20 K using momentum dependent electron energy-loss spectroscopy. Our results demonstrate the presence of fi…
