Compositional Control and Optimization of Molecular Beam Epitaxial Growth of (Sb2Te3)x(MnSb2Te4)y Magnetic Topological Insulators
Ido Levy, Candice Forrester, Haiming Deng +6
Magnetic topological insulators such as MnBi2Te4 and MnSb2Te4 are promising hosts of novel physical phenomena such as quantum anomalous Hall effect and intrinsic axion insulator st…
Designer topological insulator with enhanced gap and suppressed bulk conduction in Bi2Se3/Sb2Te3 ultra-short period superlattices
Ido Levy, Cody Youmans, Thor Garcia +6
A novel approach to reduce bulk conductance by the use of short period superlattices (SL) of two alternating topological insulator layers is presented. Evidence for a superlattice…
Giant Fine Structure Splitting of the Bright Exciton in a Bulk MAPbBr Single Crystal
Michal Baranowski, Krzysztof Galkowski, Alessandro Surrente +13
Exciton fine structure splitting in semiconductors reflects the underlying symmetry of the crystal and quantum confinement. Since the latter factor strongly enhances the exchange i…
Hole - Nuclear Spin Interaction in Quantum Dots
B. Eble, C. Testelin, P. Desfonds +7
We have measured the carrier spin dynamics in p-doped InAs/GaAs quantum dots by pump-probe photo-induced circular dichroism and time-resolved photoluminescence experiments. We show…
Inversion of the spin polarization of localized electrons driven by dark excitons
B. Eble, C. Testelin, F. Bernardot +2
The creation of free excitons by absorption of circularly polarized photons, and their subsequent fast capture by donors, is at the origin of the spin polarization of donor-bound e…
Signature of the Overhauser field on the coherent spin dynamics of donor-bound electron in a single CdTe quantum well
C. Testelin, F. Bernardot, G. Karczewski +1
We have studied the coherent spin dynamics in an oblique magnetic field of electrons localized on donors and placed in the middle of a single CdTe quantum well, by using a time-res…
