WebbIl microscopio a effetto tunnel (STM, dall'inglese Scanning Tunneling Microscope) è un potente strumento per lo studio delle superfici a livello atomico. Il suo sviluppo nel 1981 fruttò ai suoi inventori, Gerd Binnig e Heinrich Rohrer (all' IBM di Zurigo), il Premio Nobel per la Fisica nel 1986. WebbScanning tunneling microscopy (STM) is a tool that profoundly shaped nanoscience and nano- technology. Since its invention by Rohrer and Binnig [1, 2, 3], for which they were awarded the 1986 Nobel prize in Physics, STM experienced revolutionary developments allowing to see for the first time nanostructures at the atomic scale.

WebbBy means of high-resolution scanning tunneling spectroscopy and quasiparticle interference, we discover an unexpected state residing below the conduction band and right within the CDW gap region. As corroborated by our theoretical analysis, this mysterious phenomenon is in good agreement with the electron-exciton coupling. WebbWe present a theory for the scanning tunneling microscope ~STM! current based on a Keldysh Green function formalism. In our formalism, we solve self-consistently an ab initio linear combination of atomic orbitals Hamiltonian within a local density formalism.

Webb4 mars 2024 · Scanning tunneling microscopy (STM) is a technique that can be used to directly observe individual biomolecules at near-molecular scale. Within this framework, STM is of crucial significance because of its role in the structural analysis, the understanding the imaging formation, and the development of relative techniques.
