Description
This book presents
the transport studies of topological insulator thin films grown by molecular
beam epitaxy. Through band structure engineering, the ideal topological
insulators, (Bi1 xSbx)2Te3 ternary alloys, are successfully fabricated, which
possess truly insulating bulk and tunable conducting surface states. Further
transport measurements on these ternary alloys reveal a disentanglement between
the magnetoelectric and thermoelectric properties. In magnetically doped
topological insulators, the fascinating quantum anomalous Hall effect was
experimentally observed for the first time. Moreover, the topology-driven
magnetic quantum phase transition was Systematically controlled by varying the
strength of the spin-orbital coupling. Readers will not only benefit from the
description of the technique of transport measurements, but will also be inspired by
the understanding of topological insulators.
