Large magnetic gap at the Dirac point in a Mn-induced BiTe heterostructure
E. D. L. Rienks, S. Wimmer, P. S. Mandal +15
Magnetically doped topological insulators enable the quantum anomalous Hall effect (QAHE) which provides quantized edge states for lossless charge transport applications. The edge…
Interband absorption edge in topological insulators Bi(TeSe)
A. Dubroka, O. Caha, M. Hronček +7
We have investigated the optical properties of thin films of topological insulators BiTe, BiSe and their alloys Bi(TeSe) on BaF su…
Nonmagnetic band gap at the Dirac point of the magnetic topological insulator (BiMnSe
J. Sánchez-Barriga, A. Varykhalov, G. Springholz +17
Magnetic doping is expected to open a band gap at the Dirac point of topological insulators by breaking time-reversal symmetry and to enable novel topological phases. Epitaxial (Bi…
Excitation intensity dependence of photoluminescence spectra of SiGe quantum dots grown on prepatterned Si substrates: Evidence for biexcitonic transition
P. Klenovský, M. Brehm, V. Křápek +7
The pumping intensity (I) dependence of the photoluminescence (PL) spectra of perfectly laterally two-dimensionally ordered SiGe quantum dots on Si(001) substrates was studied. The…
