Transport Studies of the Electrical, Magnetic and Thermoelectric properties of Topological Insulator Thin Films

• Gebundenes Buch

Produktbeschreibung

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.

Autorenporträt

Jinsong Zhang received his B.Sc. in Physic in Tsinghua University, P. R. China in 2008. He obtained his Ph.D. in Physics from Physics Department of Tsinghua University in January 2014. His major research project in Prof. Yayu Wang's group was the transport studies of the electric, magnetic and thermoelectric properties in topological insulator thin films. At present, he is a post-doc fellow in Prof. Yi Cui's group in the Department of Material Science and Engineering, Stanford University. His current projects are focusing on the fabrication and characterization of two-dimensional layer materials.
