Epitaxial growth of a two-dimensional topological insulator candidate: monolayer Si2Te2
Xiaochun Huang, Rui Xiong, Klara Volckaert +9
Hexagonal Si2Te2 monolayers (ML-Si2Te2) were predicted to show strain-dependent band-crossover between semiconducting and room-temperature quantum spin Hall phases. However, invest…
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…
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…
Band gap engineering by Bi intercalation of graphene on Ir(111)
Jonas Warmuth, Albert Bruix, Matteo Michiardi +7
We report on the structural and electronic properties of a single bismuth layer intercalated underneath a graphene layer grown on an Ir(111) single crystal. Scanning tunneling micr…
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…
Controllable magnetic doping of the surface state of a topological insulator
T. Schlenk, M. Bianchi, M. Koleini +11
A combined experimental and theoretical study of doping individual Fe atoms into Bi2Se3 is presented. It is shown through a scanning tunneling microscopy study that single Fe atoms…
