September 2017 – Scanning tunneling microscopy of in-situ exfoliated VSe2 reveals a non monotonic thickness dependence of the charge density wave (CDW) order parameter and phase transition temperature. Both parameters are extracted directly form the charge modulation amplitude imaged in STM micrographs. This study lifts the contradictions of previous experiments claiming opposite thickness dependencies of…

August 2017 – Reduced dimensions can give rise to surprising effects. While a long exposure time photograph of a macroscopic moving object appears blurred, scanning tunneling microscopy images of flipping Si dimer defects embedded in Bi-nanolines on the Si(001) surface appear much sharper than those of static ones. This counter intuitive dynamic sharpening is perfectly…

January 2017 – Combining scanning tunneling microscopy (STM) and density functional theory, we unambiguously identify Cu intercalated on the octahedral site in the van der Waals gap of 1T-CuxTiSe2. STM imaging shows that at low Cu content (x5%) it forms short-range ordered domains which tend to be phase shifted. Tunneling spectroscopy shows a well developed…

March 2016 – Scanning tunnelling spectroscopy on very homogeneous Y123 at 0.4K lift the veil on the vortex core spectroscopy. We find that the subgap features which have been challenging theoretical modelling for over twenty years do in fact not belong to vortices: they are observed everywhere along the surface with high spatial and energy…
