Anionic Character of the Conduction Band of Sodium Chloride
Christopher C. Leon, Abhishek Grewal, Klaus Kuhnke +2
The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atom…
Character of electronic states in the transport gap of molecules on surfaces
Abhishek Grewal, Christopher C. Leon, Klaus Kuhnke +2
We report on scanning tunneling microscopy (STM) topographs of individual metal phthalocyanines (MPc) on a thin salt (NaCl) film on a gold substrate, at tunneling energies within t…
Tracking a Spin-Polarized Superconducting Bound State across a Quantum Phase Transition
Sujoy Karan, Haonan Huang, Alexander Ivanovic +5
The magnetic exchange coupling between magnetic impurities and a superconductor induce so-called Yu-Shiba-Rusinov (YSR) states which undergo a quantum phase transition (QPT) upon i…
Real-Time Tracking of Coherent Oscillations of Electrons in a Nanodevice by Photo-assisted Tunnelling
Yang Luo, Frank Neubrech, Alberto Martin-Jimenez +3
Coherent collective oscillations of electrons excited in metallic nanostructures (localized surface plasmons) can confine incident light to atomic scales and enable strong light-ma…
