Inverse photoemission spectroscopy at metal/acetonitrile interface by hole injection through solution species

Polarization at the gold/pentacene interface

Direct and inverse photoemission spectroscopy are used to investigate the electronic polarization P = P + P induced by the pentacene anion and cation at the Au/pentacene interface. Based on the spectroscopic measurements and on previously published calculations, we determine that the total polarization at the metal interface is approximately 0.67 eV larger than at the surface of the pentacene f...

Inverse photoemission spectroscopy at the platinum/acetonitrile interface with several redox couples

Electronic structures at the interface between Au and CH3NH3PbI3.

The electronic properties of interfaces formed between Au and organometal triiodide perovskite (CH3NH3PbI3) are investigated using ultraviolet photoemission spectroscopy (UPS), inverse photoemission spectroscopy (IPES) and X-ray photoemission spectroscopy (XPS). It is found that the CH3NH3PbI3 film coated onto the substrate of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS)/...

Role of metal–molecule chemistry and interdiffusion on the electrical properties of an organic interface: The Al–F16CuPc case

The chemistry and electronic structure of interfaces between Al and copper hexadecafluorophthalocyanine (F16CuPc) are studied via x-ray photoemission spectroscopy, ultraviolet photoemission spectroscopy ~UPS!, and current–voltage measurements. Electron injection barriers measured by UPS are reported. Analysis of the Al–F16CuPc reaction shows the formation of a phase of three-dimensional (F16CuP...

Interface energetics of polyfluorene and fluorene-arylamine copolymers

The energy level alignment at interfaces between poly(9,9’-dioctylfluorene) (F8), poly(9,9'-dioctylfluorene-co-bisN,N '-(4-butylphenyl)-diphenylamine) (TFB) and poly(9,9’-dioctylfluorene-co-bis-N,N’-(4-butylphenyl)-bis-N,N’phenyl-1,4-phenylenediamine) (PFB) and substrates with work function ranging from 4.3 eV to 5.1 eV is investigated via ultra-violet photoemission spectroscopy. Vacuum level a...
