<p>This book presentsthe transport studies of topological insulator thin films grown by molecularbeam epitaxy. Through band structure engineering, the ideal topologicalinsulators, (Bi1−xSbx)2Te3 ternary alloys, are successfully fabricated, whichpossess truly insulating bulk and tunable conducting surface states. Furthertransport measurements on these ternary alloys reveal a disentanglement betweenthe magnetoelectric and thermoelectric properties. In magnetically dopedtopological insulators, the fascinating quantum anomalous Hall effect wasexperimentally observed for the first time. Moreover, the topology-drivenmagnetic quantum phase transition was Systematically controlled by varying thestrength of the spin-orbital coupling. Readers will not only benefit from thedescription of the technique of transport measurements, but will also be inspired bythe understanding of topological insulators.</p>
