Signatures of modulated pair interaction in cuprate superconductors
, 2006 Recent low-temperature scanning tunnelling spectroscopy experiments on the surface of BSCCO-2212 have revealed a strong positive correlation between the position of localized resonances at -960 meV identified with interstitial oxygen dopants and the size

Dopant‐Catalyzed Singlet Exciton Fission
ChemPhysChem, 2016 AbstractIn acene‐based molecular crystals, singlet exciton fission occurs through superexchange mediated by two virtual charge‐transfer states. Hence, it is sensitive to their energies, which depend on the local environment. The crucial point is the balance between the charge–quadrupole interactions within the pair of molecules directly involved in the

Controlling doping in graphene through a SiC substrate: A first-principles study
, 2011 Controlling the type and density of charge carriers by doping is the key step for developing graphene electronics. However, direct doping of graphene is rather a challenge. Based on first-principles calculations, a concept of overcoming doping difficulty

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
