Electron delocalization in a 2D Mott insulator
Cosme G. Ayani, Michele Pisarra, Iván M. Ibarburu +5
The prominent role of electron-electron interactions in two-dimensional (2D) materials versus three-dimensional (3D) ones is at the origin of the great variety of fermionic correla…
Unveiling the inter-layer interaction in a 1H/1T TaS van de Waals heterostructure
Cosme G. Ayani, M. Bosnar, F. Calleja +11
This study delves into the intriguing properties of 1H/1T-TaS van der Waals heterostructure, focusing on the transparency of the 1H layer to the Charge Density Wave of the unde…
Metastable polymorphic phases in monolayer TaTe2
Iolanda Di Bernardo, Joan Ripoll-Sau, Fabian Calleja +6
Polymorphic phases and collective phenomena - such as charge density waves (CDWs) - in transition metal dichalcogenides (TMDs) dictate the physical and electronic properties of the…
Switchable molecular functionalization of an STM tip: from a Yu-Shiba-Rusinov tip to a Kondo tip
Cosme. G. Ayani, Fabian Calleja, Ivan M. Ibarburu +6
In this work we fabricate and characterize a functionalized superconducting (SC) Nb tip of a scanning tunnelling microscope (STM). The tip is functionalized with a Tetracyanoquinod…
Probing the phase transition to a coherent 2D Kondo lattice
Cosme G. Ayani, Michele Pisarra, Iván M. Ibarburu +5
Strongly correlated materials exhibit exotic electronic states arising from the strong correlation between electrons. Dimensionality provides a tuning knob because thinning down to…
Thermally Activated Processes for Ferromagnet Intercalation in Graphene-Heavy Metal Interfaces
F. Ajejas, A. Anadón, A. Gudin +11
The development of graphene (Gr) spintronics requires the ability to engineer epitaxial Gr heterostructures with interfaces of high quality, in which the intrinsic properties of Gr…
Robust, switchable, C-related, Superconducting Nanostructure at the Apex of a W tip
C. G. AYani, F. Calleja, P. Casado +8
We report on a controlled method to fabricate in-situ a superconducting (SC) nanostructure at the apex of the standard W tip of a Scanning Tunnelling Microscope (STM) by pulsing th…
