Angle-Resolved Photoemission Spectroscopy Studies of 2D Material Heterostructures [Paperback]

This book focuses on angle-resolved photoemission spectroscopy studies on novel interfacial phenomena in three typical two-dimensional material heterostructures: graphene/h-BN, twisted bilayer graphene, and topological insulator/high-temperature superconductors. Since the discovery of graphene, two-dimensional materials have proven to be quite a large family. As an alternative to searching for other family members with distinct properties, the combination of two-dimensional (2D) materials to construct heterostructures offers a new platform for achieving new quantum phenomena, exploring new physics, and designing new quantum devices. By stacking different 2D materials together and utilizing interfacial periodical potential and order-parameter coupling, the resulting heterostructures electronic properties can be tuned to achieve novel properties distinct from those of its constituent materials. This book offers a valuable reference guide for all researchers and students working in thearea of condensed matter physics and materials science.

Eryin Wang received his PHD in physics from Tsinghua University. During PHD, he utilized angle-resolved photoemission spectroscopy (ARPES) and nanospot ARPES to study the novel interfacial phenomena in 2D material heterostructures, including Bi2Se3/BSCCO and Graphene/h-BN. Now he is working in Max Planck Institute for the Structure and Dynamics of Matter as a receiver of Humboldt Research Fellowship. Currently, he is combining ultrafast transport and molecular beam epitaxy techniques to investigate the light-induced superconductivity in organicl“¹
