Designer topological insulator with enhanced gap and suppressed bulk conduction in Bi2Se3/Sb2Te3 ultra-short period superlattices
Ido Levy, Cody Youmans, Thor Garcia +6
A novel approach to reduce bulk conductance by the use of short period superlattices (SL) of two alternating topological insulator layers is presented. Evidence for a superlattice…

Self-assembled Bismuth Selenide (Bi2Se3) quantum dots grown by molecular beam epitaxy
Marcel S. Claro, Abhinandan Gangopadhyay, David J. Smith +1
We report the growth of self-assembled Bi2Se3 quantum dots (QDs) by molecular beam epitaxy on GaAs substrates using the droplet epitaxy technique. The QD formation occurs after ann…
