One-dimensional Dirac modes in the core of a pentagonal topological crystalline insulator nanowire
Saeed Samadi, Rafał Rechciński, Marta A. Chabowska +1
We investigate the electronic band topology of recently fabricated pentagonal IV-VI semiconductor nanowires, which contain five radial twin planes meeting at the nanowire…
Topological states on uneven (Pb,Sn)Se (001) surfaces
Rafał Rechciński, Ryszard Buczko
The impact of surface morphology on electronic structure of topological crystalline insulators is studied theoretically. As an example, the structure of topologically protected ele…
Fragility of the Dirac Cone Splitting in Topological Crystalline Insulator Heterostructures
Craig M. Polley, Ryszard Buczko, Alexander Forsman +11
The 'double Dirac cone' 2D topological interface states found on the (001) faces of topological crystalline insulators such as PbSnSe feature degeneracies located awa…
Observation of topological crystalline insulator surface states on (111)-oriented PbSnSe films
C. M. Polley, P. Dziawa, A. Reszka +13
We present angle resolved photoemission spectroscopy measurements of the surface states on in-situ grown (111) oriented films of PbSnSe, a three dimensional topologic…
PbTe/PbSnTe heterostructures as analogs of topological insulators
Ryszard Buczko, Łukasz Cywiński
We investigate theoretically the PbTe/PbSnTe heterostructure grown in [111] direction, specifically a quantum wall (potential step of width d) of PbTe embedded in Pb_{1-x}Sn_{x}Te.…
