Introduction, properties. Such states are characterized by topological invariants in terms of the bulk electronic states. In this chapter, we describe the fundamental properties of three-dimensional topological insulators. From the theoretical aspect, we review the exotic electromagnetic responses originating fr

Experimental Methods,eam epitaxy thin-film heterostructure growth, photo-lithography device fabrication, low-temperature electrical transport measurements, and time-domain terahertz spectroscopy. Furthermore, x-ray and neutron experiments are powerful ways to inspect the quality of our novel heterostructures. In this ch

Magnetic Modulation Doping for Quantum Anomalous Hall Effect,om an energy gap formation in the topological surface state with broken time-reversal symmetry. Although the size of the magnetic gap has been reported to be about 50 meV, the observable temperature of the QAH effect has been limited below 100 mK. In this chapter, we develop a Cr magnetic modulation

Magnetic Proximity Induced Quantum Anomalous Hall Effect,he non-magnetic material also becomes magnetic through an exchange coupling with the spin-polarized electronic states in the magnet. For topological insulators (TIs), the magnet is necessary to be a magnetic insulator to prevent the electric current flow in the magnetic layer. An advantage of the pr

Magnetic Modulation Doping for Quantum Anomalous Hall Effect,d to be about 50 meV, the observable temperature of the QAH effect has been limited below 100 mK. In this chapter, we develop a Cr magnetic modulation doping technique to enhance the observable temperature of the QAH effect. In addition, we introduce the recent experimental discoveries enabled by the higher temperature QAH effect.

Summary,henomena. Furthermore, in contrast to the standard uniformly doped system, we magnetically control the top/bottom surface degrees of freedom, which dramatically enriches the variation of quantized phenomena in magnetic TIs.
