Observation of charge density wave excitonic order parameter in topological insulator monolayer WTe2
Liam Watson, Joan Ripoll, Zhengjue Tong +12
Strong electron-hole interactions in a semimetal or narrow-gap semiconductor may drive a ground state of condensed excitons. Monolayer WTe2 has been proposed as a host material for…
Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe
Marc G. Cuxart, Roberto Robles, Beatriz Muñiz Cano +8
MnTe has recently emerged as a canonical altermagnet, a newly identified class of magnetism characterized by compensated antiferromagnetic order coexisting with spin-split electron…
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…
Engineering a Spin-Orbit Bandgap in Graphene-Tellurium Heterostructures
B. Muñiz Cano, D. Pacilè, M. G. Cuxart +13
Intensive research has focused on harnessing the potential of graphene for electronic, optoelectronic, and spintronic devices by generating a bandgap at the Dirac point and enhanci…
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…
Native point defects and their implications for the Dirac point gap at MnBiTe(0001)
M. Garnica, M. M. Otrokov, P. Casado Aguilar +13
The Dirac point gap at the surface of the antiferromagnetic topological insulator MnBiTe is a highly debated issue. While the early photoemission measurements reported on l…
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…
