Optical control of conductivity type and valley polarization via persistent photoconductivity in (Pb,Sn)Se quantum wells
Alexander Kazakov, Gauthier Krizman, Valentine V. Volobuev +8
The ability to tune the Fermi level of semiconductors is at the heart of modern electronics. Here, we demonstrate that persistent photoconductivity (PPC) enables tuning of carrier…
From many valleys to many topological phases - quantum anomalous Hall effect in IV-VI semiconductor quantum wells
Szymon Majewski, Michał Wierzbicki, Tomasz Dietl
Consistent with prior qualitative expectations for group IV-VI topological crystalline insulators, this work demonstrates, based on band structure and Chern number calculations, th…
Theory of bound magnetic polarons in cubic and uniaxial antiferromagnets
Dawid Bugajewski, Carmine Autieri, Tomasz Dietl
Motivated by a recent debate about the origin of remanent magnetization and the corresponding anomalous Hall effect in antiferromagnets and altermagnets, a theory of bound magnetic…
Topological phase diagram and quantum magnetotransport effects in (Pb,Sn)Se quantum wells with magnetic barriers (Pb,Eu)Se
Alexander Kazakov, Valentine V. Volobuev, Chang-Woo Cho +6
In this study, we report here on a successful growth by molecular beam epitaxy of high crystalline quality PbSnSe:Bi/PbEuSe QWs with and $y =…
Role of magnetic doping in topological HgTe and application of the Gram-Schmidt method for computing impurity states in quantum wells
Dawid Bugajewski, Tomasz Dietl
The quantum spin Hall effect in non-magnetic and Mn-doped HgTe quantum well is strongly affected by Kondo scattering of edge electrons by holes localized on acceptors. A generalize…
Magnetic-field-induced topological phase transition in Fe-doped (Bi,Sb)Se heterostructures
Y. Satake, J. Shiogai, G. P. Mazur +9
Three-dimensional topological insulators (3D-TIs) possess a specific topological order of electronic bands, resulting in gapless surface states via bulk-edge correspondence. Exotic…
Experimental search for the origin of low-energy modes in topological materials
G. P. Mazur, K. Dybko, A. Szczerbakow +9
Point-contact spectroscopy of several non-superconducting topological materials reveals a low temperature phase transition that is characterized by a Bardeen-Cooper-Schrieffer-type…
