Systems of adatoms on semiconductor surfaces display competing ground states and exotic spectral properties typical of two-dimensional correlated electron materials which are …
We investigate the bilayer Ruddlesden-Popper iridate Sr 3 Ir 2 O 7 by temperature- dependent angle-resolved photoemission. At low temperatures, we find a fully gapped …
Electronic correlations together with dimensional constraints lead to some of the most fascinating properties known in condensed matter physics. As possible candidates where …
We take advantage of complementary high-resolution experimental techniques and theoretical tools to get insight into the α-Sn/Ge (111) triangular lattice surface consisting of …

The result of a physical measurement depends on the time scale of the experimental probe. In solid-state systems, this simple quantum mechanical principle has far-reaching …
We show that each surface atom of heavily boron-doped,(111)-oriented silicon with a√ 3×√ 3 reconstruction has electrically switchable two charge states due to the strong electron …
