Introducing antiferromagnetic ordering on the surface states of Bi2Se3 topological insulator by Europium doping

Autor: Paul, Sumana, Das, Moumita, Datta, Sujoy, Chakraborty, Raja, Mandal, Prabhat, Giri, P. K.

Topological insulators (TIs) are materials with an insulating bulk characterized by a gapped band structure, along with gapless metallic surface states having a Dirac cone with a helical spin structure in momentum space. The helical spin--momentum lo

Nitrogenated CQD decorated ZnO nanorods towards rapid photodegradation of rhodamine B: a combined experimental and theoretical approach

Autor: Mandal, Sujoy Kumar, Paul, Sumana, Datta, Sujoy, Jana, Debnarayan

Publikováno v: Applied Surface Science 563, 150315 (2021)

In this work, hybridization of nonmetal nitrogen-doped carbon dots (NCQDs) with ZnO nanorods (NRs) is utilized towards better photocatalytic degradation of rhodamine B under ultraviolet (UV) irradiation. The structural characterization is confirmed b
