    Robust topological phase in proximitized core–shell nanowires coupled to multiple superconductors 
    Stanescu, Tudor D; Sitek, Anna; Manolescu, Andrei (Beilstein Institut, 2018-05-22)
    We consider core–shell nanowires with prismatic geometry contacted with two or more superconductors in the presence of a magnetic field applied parallel to the wire. In this geometry, the lowest energy states are localized on the outer edges of the ...

    SiGe nanocrystals in SiO2 with high photosensitivity from visible to short-wave infrared 
    Stavarache, Ionel; Logofatu, Constantin; Sultan, Muhammad Taha; Manolescu, Andrei; Svavarsson, Halldor; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia (Springer Science and Business Media LLC, 2020-02-24)
    Films of SiGe nanocrystals (NCs) in oxide have the advantage of tuning the energy band gap by adjusting SiGe NCs composition and size. In this study, SiGe-SiO2 amorphous films were deposited by magnetron sputtering on Si substrate followed by rapid ...

    Skyrmion lifetime in ultrathin films 
    von Malottki, Stephan; Haldar, Soumyajyoti; Delin, Anna; Heinze, Stefan; Bessarab, Pavel (American Physical Society (APS), 2019-02-26)
    We show that thermal stability of skyrmions due to entropic effects can be strongly affected by external control parameters such as magnetic field and interface composition. The lifetimes of isolated skyrmions in atomic Pd/Fe bilayers on Ir(111) and ...

    Terahertz Time-Domain Spectroscopy of Graphene Nanoflakes Embedded in Polymer Matrix 
    Koroliov, Anton; Chen, Genyu; Goodfellow, Kenneth M.; Vamivakas, A. Nick; Staniszewski, Zygmunt; Sobolewski, Peter; Fray, Mirosława El; Łaszcz, Adam; Czerwinski, Andrzej; Richter, Christiaan; Sobolewski, Roman (MDPI AG, 2019-01-23)
    The terahertz time-domain spectroscopy (THz-TDS) technique has been used to obtain transmission THz-radiation spectra of polymer nanocomposites containing a controlled amount of exfoliated graphene. Graphene nanocomposites (1 wt%) that were used in ...

    Thermoelectric current in topological insulator nanowires with impurities 
    Erlingsson, Sigurdur I.; Bardarson, Jens H; Manolescu, Andrei (Beilstein Institut, 2018-04-12)
    In this paper we consider charge current generated by maintaining a temperature difference over a nanowire at zero voltage bias. For topological insulator nanowires in a perpendicular magnetic field the current can change sign as the temperature of one ...
