2D Theoretically Twistable Material Database
Yi Jiang, Urko Petralanda, Grigorii Skorupskii +30
The study of twisted two-dimensional (2D) materials, where twisting layers create moiré superlattices, has created opportunities for investigating topological phases and strongly c…
Two-dimensional Topological Quantum Chemistry and Catalog of Topological Materials
Urko Petralanda, Yi Jiang, Hanqi Pi +4
Two-dimensional topological materials host symmetry-protected, disorder-robust edge states cen- tral to quantum technologies. Yet, they remain scarce compared with their three-dime…
Imaging the Electric Field with X-Ray Diffraction Microscopy
Trygve Magnus Ræder, Urko Petralanda, Thomas Olsen +1
The properties of semiconductors and functional dielectrics are defined by their response in electric fields, which may be perturbed by defects and the strain they generate. In thi…
Two-dimensional ferroelectrics from high throughput computational screening
Mads Kruse, Urko Petralanda, Morten N. Gjerding +3
We report a high throughput computational search for two-dimensional ferroelectric materials. The starting point is 252 pyroelectric materials from the computational 2D materials d…
Polarization switching induced by domain wall sliding in two-dimensional ferroelectric monochalcogenides
Urko Petralanda, Thomas Olsen
The ability to switch between distinct states of polarization comprises the defining property of ferroelectrics. However, the microscopic mechanism responsible for switching is not…
Abundance of second order topology in symmetric two-dimensional insulators
Joachim Sødequist, Urko Petralanda, Thomas Olsen
We have screened 71 two-dimensional (2D) materials with symmetry for non-trivial second order topological order and find that 28 compounds exhibit an obstructed atomic limit…
