ABSTRACT

Various materials and nanostructures with large Rashba coefficient are a subject of study in spintronic material science as they present templates for voltage-controlled spintronic applications. Some of these material systems were mentioned in Chapter 3. There is a specific class of semiconductors called topological insulators (TI) that presents new opportunities to spintronics. TI surface electron states experience a strong spin-orbit interaction and can be manipulated by an external electric field. A large linear-k Rashba coefficient has been reported in Bi2Te3-based TI [1].
