Spin-Polarized Tunneling Study on Spin-Momentum Locking in the Topological Insulators
Luqiao Liu, A. Richardella, Ion Garate +3
We demonstrate that the charge-spin conversion efficiency of topological insulators (TI) can be experimentally determined by injecting spin-polarized tunneling electrons into a TI.…
Surface-to-bulk scattering in topological insulator films
Kush Saha, Ion Garate
We present a quantitative microscopic theory of the disorder- and phonon-induced coupling between surface and bulk states in topological insulator (TI) films. We find a simple stru…
Experimental evidence and control of the bulk-mediated intersurface coupling in topological insulator Bi2Te2Se nanoribbons
Zhaoguo Li, Ion Garate, Jian Pan +14
Nearly a decade after the discovery of topological insulators (TIs), the important task of identifying and characterizing their topological surface states through electrical transp…
Phonon-induced topological insulation
Kush Saha, Ion Garate
We develop an approximate theory of phonon-induced topological insulation in Dirac materials. In the weak coupling regime, long wavelength phonons may favor topological phases in D…
