Radical-Induced Changes in Transition Metal Interfacial Magnetic Properties: A Blatter Derivative on Polycrystalline Cobalt
Ewa Malgorzata Nowik-Boltyk, Tobias Junghoefer, Erika Giangrisostomi +5
In this work, we study the cobalt radical interface obtained by depositing a monolayer of a derivative of the Blatter radical on polycrystalline cobalt. By examining the occupied a…
Fermi surface tomography
Sergey Borisenko, Alexander Fedorov, Andrii Kuibarov +19
Fermi surfaces, three-dimensional (3D) abstract interfaces that define the occupied energies of electrons in a solid, are important for characterizing and predicting the thermal, e…
Temperature-dependent electronic ground state charge transfer in van der Waals heterostructures
Soohyung Park, Haiyuan Wang, Thorsten Schultz +15
Electronic charge rearrangement between components of a heterostructure is the fundamental principle to reach the electronic ground state. It is acknowledged that the density of st…
