Physicochemical analysis of Bi2Te3 – (Fe, Eu) – Bi2Te3 junctions grown by molecular beam epitaxy method [PDF]
AIP Advances, 2017 Topological insulators (TI) are a class of materials gaining in importance due to their unique spin/electronic properties, which may allow for the generation of quasiparticles and electronic states which are not accessible in classical condensed-matter systems. Not surprisingly, TI are considered as promising materials for multiple applications in next
