Experimental detection of surface spin-polarized electron accumulation in topological insulators using scanning tunneling microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
Spin-momentum locking in the surface mode of topological insulators (TI) leads to the surface accumulation of spin-polarized electrons caused by bias current flows through TI sampl…
Study Of Surface Spin-Polarized Electron Accumulation In Topological Insulators Using Scanning Tunneling Microscopy
S. Tyagi, M. Dreyer, D. Bowen +6
The results of scanning tunneling microscopy experiments using iron-coated tungsten tips and current-carrying bismuth selenide () samples are reported. Asymmetry in tunne…
