One-way electron mirrors from single-layer stacking shifts in rhombohedral graphite
Konrád Kandrai, András Balogh, Dóra Varga +11
One-way mirrors or asymmetric scatterers are key components of photonic systems, protecting sources from back-reflections and routing light along a chosen path. Acoustic systems ca…
Ultrastrong Au-Te bonding drives disorder in monolayer ZrTe on gold
Konrád Kandrai, Zoltán Tajkov, Péter Kun +3
Monolayer ZrTe is predicted to host a large-gap quantum spin Hall phase, motivating efforts to isolate single layers of the material. Gold-assisted exfoliation produces clean m…
Proximity-Induced Spin Reorientation in Monolayer CrI on Hexagonal WTe
Dániel Tibor Pozsár, Marcell Balázs Sípos, Amador García-Fuente +7
Magnetic anisotropy controls the orientation and thermal stability of two-dimensional magnetic order. Predicting proximity-induced changes in anisotropy requires linking the electr…
Strain induced magnetic phase transitions in Fe3GeTe2 monolayer
Anjali Jyothi Bhasu, Satish Kumar, Mátyás Török +11
We investigate the magnetic properties of a monolayer of Fe3GeTe2 as a function of the lattice constant by combining first-principles calculations with atomistic spin dynamics simu…
The role of stacking and strain in mean-field magnetic moments of multilayer graphene
András Balogh, János Koltai, Péter Nemes-Incze +1
Rhombohedral or ABC stacked multilayer graphene hosts a correlated magnetic ground state at charge neutrality, making it one of the simplest systems to investigate strong electroni…
Identification of graphite with perfect rhombohedral stacking by electronic Raman scattering
András Pálinkás, Krisztián Márity, Konrád Kandrai +5
Rhombohedral graphite (RG) shows strong correlations in its topological flat band and is pivotal for exploring emergent, correlated electronic phenomena. One key advantage is the e…

Zoltán Kovács-Krausz, Dániel Nagy, Albin Márffy +9
The layered van der Waals material ZrTe is known as a candidate topological insulator (TI), however its topological phase and the relation with other properties such as an appa…
Mechanical strain induced topological phase changes of monolayer and bilayer ZrTe
Zoltán Tajkov, Dániel Nagy, János Koltai +1
Two-dimensional materials offer exceptional tunability of their properties through strain, electrostatic gating, and related mechanisms. Among these, ZrTe stands out as a mater…
Revealing the band structure of ZrTe using Multicarrier Transport
Zoltán Kovács-Krausz, Endre Tóvári, Dániel Nagy +9
The layered material ZrTe appears to exhibit several exotic behaviors which resulted in significant interest recently, although the exact properties are still highly debated. A…
Revealing the topological phase diagram of ZrTe using the complex strain fields of microbubbles
Zoltán Tajkov, Dániel Nagy, Konrád Kandrai +7
Topological materials host robust properties, unaffected by microscopic perturbations, owing to the global topological properties of the bulk electron system. Materials in which th…
Observation of competing, correlated ground states in the flat band of rhombohedral graphite
Imre Hagymási, Mohammad Syahid Mohd Isa, Zoltán Tajkov +10
In crystalline solids the interactions of charge and spin can result in a variety of emergent quantum ground states, especially in partially filled, topological flat bands such as…
