Atomic resolution of Au(111), illustrating the herringbone reconstruction and the quasi-particle interference from the Shockley surface state (T=1.2K)

Ultra-thin island of FeSe synthesized on Bi2Se3. The FeSe patch exhibits a square lattice, and two different types of defects, A and B, can be identified (V_S = 500mV, I_t = 300 pA, T=5 K)

Atomic resolution of a cleaved bulk NbSe_2 crystal. Superstructures correspond to the typical CDW in this material (T = 1.2 K)

Image of a single-layer of TaS_2 synthesized on Au(111), illustrating the atomic resolution and moiré pattern. There is no visible CDW in the material at 4.7 K (It=500 pA, VS=4.3 mV, T = 4.7K)

STM image of a self-assembled monolayer of manganese porphyrin catalysts at the solid/liquid interface

Image of the hexagonal nanoskyrmion lattice in a single iron layer and of the spin spiral in the iron double layer measured by spin-polarized STM using an iron tip (Vs=1mV, T=6K)

A single phthalocyanine molecule (2HPc) is “caught” at a monatomic step edge of a Ag(111) surface. The STM’s high resolution allows for mapping out its LUMO orbital. (T = 5 K)

The famous Si(111)-7x7 reconstruction was the first surface ever to be images with atomic resolution by Binning and Rohrer in the early eighties (Nobel prize 1986). (T = 5 K)

Monolayer of Pt-complex molecules on Au(111). Phosphorescent complexes are promising candidates for next-generation lighting technologies. We study electronic properties of the adsorbed molecules on conductive surfaces.  (T = 6 K)

Cu3-triplesalen molecules on Au(111). These complexes are the building block of the “Mn6Cr” single-molecule magnet. We used pulse-valve and rapid-heating techniques to deposit molecules onto clean surfaces within an ultra-high vacuum environment. (T = 6 K)

21 individual CO molecules on Cu(111) arranged by lateral manipulation using the STM tip. The Images size is 13 x 5 nm2 , i.e., the font size of the “written” text is 0.000006 pt. The bottom figure shows an atomic model of the STM image shown above. (T = 6 K)

Spectroscopic (dI/dV) map of the BiCu2/Cu(111) surface alloy. The surface exhibits several Rashba-split surface states leading to a complex standing-wave pattern. The Fourier analysis allows for determination of the band structure and Rashba parameter. (40 x 40 nm2, T = 5 K)
