This feature article deals with molecular‐beam epitaxy of (Bi,Sb)(Se,Te)‐based topological insulators (TIs) on Si substrates. Important aspects are covered, such as exploring the van der Waals growth mode, characterizing crystal defects, reducing the bulk carrier concentration, tuning the Fermi level to the Dirac point, and, finally, fabricating TI/superconductor devices fully in situ.

Analogous to the quantum Hall states, which are ballistic 1D edge modes surrounding an insulating 2D bulk, topological insulators have "special" 2D surface states around a 3D bulk.

In the one-dimensional Su-Schrieffer-Heeger model and its mirror-symmetric variant strongly localized plasmonic excitations are observed which originate from topologically nontrivial single-particle states. These Topological insulators are of interest for many applications in electronics and optoelectronics, but harnessing their unique properties requires detailed understanding and control of charge 2015-09-03 · While the general concept behind topological superconductivity predates topological insulators [121–124], recent considerations of topological band theory and related invariant structures can be used to topologically classify superconductors that are direct analogs of topological insulators (for reviews, see [3, 7, 125, 126]). 2018, Pocket/Paperback.

Techniques such as angle-resolved Topological insulators are insulating in the bulk, but process metallic states present around its boundary owing to the topological origin of the band structure. The metallic edge or surface states are immune to weak disorder or impurities, and robust against the deformation of the system geometry. 2021-04-12 · Two-and-a-half years ago, Charles Kane and Eugene Mele received the 2019 Breakthrough Prize in Fundamental Physics.The award recognized their theories that predicted the existence of topological insulators, a new class of material with the unique property of being an electrical insulator on the inside and having a surface that conducts electricity. Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducting states on their edge or surface. These states are possible due to the combination of spin-orbit interactions and time-reversal symmetry.
