Surface-State Localization at Adatoms

, 2004
Low-temperature scanning tunneling spectroscopy of magnetic and non-magnetic metal atoms on Ag(111) and on Cu(111) surfaces reveals the existence of a common electronic resonance at an energy below the binding energies of the surface states.

Near‐Field Phonon Nanoscopy and Imaging of Structural Variants in Mixed Phase BiFeO3

Advanced Functional Materials, EarlyView.
Nano‐Fourier transform infrared spectroscopy and scattering scanning near‐field optical microscopy imaging reveal the phonon response of nanoscale phase variants in mixed‐phase BiFeO3 (BFO). Direct mid‐infrared imaging of associated distinct vibrational signatures is used as a non‐invasive optical detection method for electrical switching of ...

The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...

Magnetotransport in a time-modulated double quantum point contact system

, 2010
We report on a time-dependent Lippmann-Schwinger scattering theory that allows us to study the transport spectroscopy in a time-modulated double quantum point contact system in the presence of a perpendicular magnetic field.
