Phase-Controlled Epitaxy and Anisotropic Antiferromagnetism of Polar Wurtzite MnTe
Janusz Sadowski, Jaroslaw Z. Domagala, Piotr Dziawa +8
Altermagnetic spintronics requires materials in which compensated magnetic order, symmetry-controlled electronic responses, and epitaxial tunability can be combined in experimental…
Moire based strain analysis in wurtzite GaAs -- rock-salt (Pb,Sn)Te core-shell nanowires grown by molecular beam epitaxy
Maciej Wojcik, Sania Dad, Piotr Dziawa +3
We investigate core/shell GaAs/(Pb,Sn)Te nanowire nanoheterostructures with wurtzite (wz) GaAs cores and (Pb,Sn)Te topological crystalline insulator shells. The nanostructures have…
Pentagonal nanowires from topological crystalline insulators: a platform for intrinsic core-shell nanowires and higher-order topology
