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…
Multiband theory for hexagonal germanium
Yetkin Pulcu, János Koltai, Andor Kormányos +1
The direct bandgap found in hexagonal germanium and some of its alloys with silicon allows for an optically active material within the group-IV semiconductor family with various po…
Formation of nanoribbons by carbon atoms confined in a single-walled carbon nanotube -- A molecular dynamics study
Somayeh Eskandari, János Koltai, István László +2
Carbon nanotubes can serve as one-dimensional nanoreactors for the in-tube synthesis of various nanostructures. Experimental observations have shown that chains, inner tubes, or na…
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…
Well-defined sub-nanometer graphene ribbons synthesized inside carbon nanotubes
Hans Kuzmany, Lei Shi, Miles Martinati +9
Graphene nanoribbons with sub-nanometer widths are extremely interesting for nanoscale electronics and devices as they combine the unusual transport properties of graphene with the…
Topological Phase Diagram of BiTeX--Graphene Hybrid Structures
Zoltán Tajkov, Dávid Visontai, László Oroszlány +1
Combining graphene with other novel layered materials is a possible way for engineering the band structure of charge carriers. Strong spin-orbit coupling in BiTeX compounds and the…
