In our new paper, we show the multilayer growth of surface-confined metal-organic frameworks (MOFs, MOCNs) under UHV conditions. We demonstrate how the coordination geometry and electronic structure of the Fe cations are influenced by the interlayer chemical interaction, thereby making the properties of the multilayer MOF distinct from those of the monolayer case. Support is part of the game: on graphene, the Fe-TCNQ MOF grows in Volmer-Weber (island) mode, but in Stranski-Krastanov mode (layer + islands) on Au(111).

LEEM Review

Here is our review of the analysis of self-assembled molecular layers on surfaces by LEEM/LEED.

​ProLEED Studio has been released!

​

Pavel developed a new software for the analysis of complex LEED patterns. After some time, during analysis of a tricky one, he said: "I love ProLEED. It surprises even me!"

A thesis summarizing our activities

         Here it is... enjoy!

DFPA

Dark-Field Pop Art. We are looking forward to Pavel's publication on dark-field LEEM analysis of molecular bilayers.

Nano-Octopuses

Sometimes it seems that our samples in vacuum chambers have been invaded by strange lifeforms. Octopuses in this case.

Even more complex self-assembled phase from our simple molecule

At some conditions, we can get a somewhat very puzzling structure made of our BDA molecule.
