Electron delocalization in a Mott insulator

STM2D Editor STM2D Editor 6 November 2025 |

We recently published an article (in spainsh) in the outreach journal “Muy Interesante” describing our results on highly correlated systems and the electron delocalization in a Mott insulator.

About Us

Our group is devoted to studying the properties of two-dimensional materials and their emergent physical and chemical properties. To this end, we employ a combination of advanced experimental techniques, including:

• Low-temperature scanning tunneling microscopy and spectroscopy (LT-STM/STS)

• Thin-film growth by molecular beam epitaxy (MBE) under ultra-high vacuum (UHV) conditions

• Angle-resolved photoemission spectroscopy (ARPES) and X-ray photoemission spectroscopy (XPS) measurements conducted at leading synchrotron facilities
