Surface States in Strain-Induced Nodal-Line Topological Semiconductors
Vitaly N. Golovach, Alexander Khaetskii
This work explores the topological phase diagram of inverted-band-gap semiconductors under strain and spin-orbit coupling. Using a minimalistic Luttinger Hamiltonian model, we foll…
Negative magnetoresistance in strained -Sn and -SnGe films in an in-plane magnetic field
Sunny Phan, Andrei Kogan, Jesse Thompson +3
To test the hypothesis that the chiral anomaly is responsible for negative magnetoresitance (MR) in \atn{}, we have studied magnetotransport in strained, epitaxial films of pure \a…
Interplay between strain and size quantization in a class of topological insulators based on inverted-band semiconductors
Alexander Khaetskii, Vitaly Golovach, Arnold Kiefer
We consider surface states in semiconductors with inverted-band structures, such as -Sn and HgTe. The main interest is the interplay of the effect of a strain of an arbitrary si…
Revisiting the physical origin and nature of surface states in inverted-band semiconductors
Alexander Khaetskii, Vitaly Golovach, Arnold Kiefer
We revisit the problem of surface states in semiconductors with inverted band structures, such as -Sn and HgTe. We unravel the confusion that arose over the past decade regardin…
Thermal Magnetic Fluctuations of a Ferroelectric Quantum Critical Point
Alexander Khaetskii, Vladimir Juricic, Alexander V. Balatsky
Entanglement of two different quantum orders is of an interest of the modern condensed matter physics. One of the examples is the dynamical multiferroicity, where fluctuations of e…
Killing Auger recombination in nanostructures by carrier spin polarization
Alexander Khaetskii, Igor Žutić
In semiconductor nanostructures nonradiative Auger recombination is enhanced by the presence of boundaries which relax the momentum conservation and thereby removes the threshold r…
