Description du livre
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.
