Large Tunable Rashba Spin Splitting of a Two-Dimensional Electron Gas in Bi2Se3
2011 (English)In: Physical Review Letters, Vol. 107, 096802Article in journal (Refereed) Published
We report a Rashba spin splitting of a two-dimensional electron gas in the topological insulator Bi2Se3 from angle-resolved photoemission spectroscopy. We further demonstrate its electrostatic control, and show that spin splittings can be achieved which are at least an order-of-magnitude larger than in other semiconductors. Together these results show promise for the miniaturization of spintronic devices to the nanoscale and their operation at room temperature.
