Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells

Advanced Functional Materials, EarlyView.
Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational

Ion irradiation effects in diamond

Surface and Coatings Technology, 1990
Abstract Diamond has long been regarded as relatively resistant to radiation, although it does undergo structural damage when bombarded by neutrons or ions. Diamond powders have been irradiated by various noble gas ions at 1–3 MeV energy and X-ray diffraction studies have shown that the lattice expansion of ion-irradiated diamond saturates with ...

Quasicrystalline transformation by ion irradiation

Physical Review B, 1986
Amorphous $\mathrm{Al}\ensuremath{-}M$ films, where $M=\mathrm{Cr}, \mathrm{Mn}, \mathrm{and} \mathrm{Fe}$, were made by coevaporation and by room-temperature ion irradiation of multilayer films. The amorphous phase was transformed into the quasicrystalline state by ion-beam-assisted thermal anneals.

The Clustering of Ions in Irradiated Gases

Radiation Research, 1959
The general theory of the clustering of ions in irradiated gases is considered. A systematic comparison of theory with experiment is impossible due to lack of data, however a limited comparison is made, and a brief consideration of the effects of clustering on the radiation chemistry of gases is given.

Ion irradiation of polymers

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991
Abstract The keV-MeV ion irradiation of polymers produces deep changes in their physical and chemical properties associated with the breaking and rearrangement of original bonds. The modification of chain structure occurs within a well defined ion fluence range which depends on the ion linear energy transfer as well as on the target parameters.

Ion irradiation experiments

Advances in Space Research, 1993
Abstract We report new results from recent experimental studies on physico-chemical effects induced in frozen gases and mixtures (CO, CO2, CH4, H2O and SO2) simulating ice targets in space (frosts on external planets and satellites, and comets). In particular we have studied, by UV-Vis-IR spectroscopy, the formation of new molecules, the alteration ...

Optical constants in ion-irradiated graphite

Surface and Coatings Technology, 1994
Abstract The ion-beam-induced amorphization of crystalline graphite layers was studied by using near-IR visible and near-UV reflectance spectra to obtain the real and imaginary parts of the refractive index as a function of photon energy in the range 0.5–7 eV.
