Single crystal studies and electronic structure investigation of a room-temperature semiconductor NaMnAs
J. Volny, V. Holy, K. Charvatova +11
We report synthesis of single crystalline NaMnAs, confirm its antiferromagnetic order and characterise the sample by photoemission spectroscopy. The electronic structure was studie…
Local geometry around B atoms in B/Si(111) from polarized x-ray absorption spectroscopy
Saleem Ayaz Khan, Martin Vondráček, Peter Blaha +4
The arrangement of B~atoms in a doped Si(111)-:B system was studied using near-edge x-ray absorption fine structure (NEXAFS). Boron atoms were…
Influence of an anomalous temperature-dependence of the phase coherence length on the conductivity of magnetic topological insulators
V. Tkáč, K. Výborný, V. Komanický +14
Magnetotransport constitutes a useful probe to understand the interplay between electronic band topology and magnetism in spintronics devices based on topological materials. A rece…
Electronic properties of Bi-doped GaAs(001) semiconductors
Jan Honolka, Conor D. Hogan, Martin Vondracek +3
Despite its potential in the fields of optoelectronics and topological insulators, experimental electronic band structure studies of Bi-doped GaAs are scarce. The reason is the com…
Non-magnetic ground state of Ni adatoms on Te-terminated bismuth chalcogenide topological insulators
M. Vondracek, J. Honolka, L. Cornils +20
We report on the quenching of single Ni adatom moments on Te-terminated Bi2Te2Se and Bi2Te3 topological insulator surfaces. The effect becomes manifested as a missing X-ray magneti…
Topological insulator homojunctions including magnetic layers: the example of n-p type (-QLs BiSe/Mn-BiSe) heterostructures
M. Valiska, J. Warmuth, M. Michiardi +9
Homojunctions between BiSe and its Mn-doped phase are investigated as a sample geometry to study the influence of spin degrees of freedom on topological insulator propertie…
Silicene vs. ordered 2D silicide: the atomic and electronic structure of the Si-/Pt(111) surface reconstruction
Martin Svec, Prokop Hapala, Martin Ondracek +8
We discuss the possibility of a 2D ordered structure formed upon deposition of Si on metal surfaces. We investigate the atomic and electronic structure of the Si-$(\sqrt{19}\times\…
