Quantum Wells for Spin Transistors
Quantum well states in the topological insulator Bi 2 Se 3 have a giant, tunable spin-splitting and may lead to room-temperature, nanoscale spintronics.
Quantum well states formed in the topological insulator Bi2Se3 which have a very large spin splitting. The size of the splitting is much bigger than in other semiconductors and this finding might open a new way to design a room-temperature nano-scale spin transistor. Spin transistors have the potential to store more data in less space and consume less power.
