Electronic Structure of Manganese Phthalocyanine Modified via Potassium Intercalation: a Comprehensive Experimental Study
Francisc Haidu, Ovidiu D. Gordan, Dietrich R. T. Zahn +5
Potassium (K) intercalated manganese phthalocyanine (MnPc) reveals vast changes of its electronic states close to the Fermi level. However, theoretical studies are controversial re…
Photoemission study of PDI8-CN2 /Au, PDI8-CN2 / Si and PDI8-CN2 - T6 interfaces
Flavia Viola Di Girolamo, Benjamin Mahns, Martin Knupfer
We report on the study of the electronic properties in PDI8-CN2 / Au, PDI8-CN2 / Si, PDI8-CN2 - T6 interfaces investigated by X-Ray (XPS) and Ultraviolet (UPS) Photoemission Spectr…
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…
Evidence for phase formation in potassium intercalated 1,2;8,9-dibenzopentacene
Friedrich Roth, Andreas König, Benjamin Mahns +2
We have prepared potassium intercalated 1,2;8,9-dibenzopentacene films under vacuum conditions. The evolution of the electronic excitation spectra upon potassium addition as measur…
Absence of photoemission from the Fermi level in potassium intercalated picene and coronene films: structure, polaron or correlation physics?
Benjamin Mahns, Friedrich Roth, Martin Knupfer
The electronic structure of potassium intercalated picene and coronene films has been studied using photoemission spectroscopy. Picene has additionally been intercalated using sodi…
Electronic structure of undoped and potassium doped coronene investigated by electron energy-loss spectroscopy
Friedrich Roth, Johannes Bauer, Benjamin Mahns +2
We performed electron energy-loss spectroscopy studies in transmission in order to obtain insight into the electronic properties of potassium intercalated coronene, a recently disc…
