报告摘要：

In this talk, Prof. Hai Wang will present the recent advances in his group with tracking and understanding the ultrafast charge carrier transport properties and their dynamics in 2D materials using terahertz spectroscopy. First, following a brief introduction to his research motivation, he will provide some basics on ultrafast THz spectroscopy and demonstrate its strength in characterization of electrical transport properties of charge carriers and low energy excitations in 2D materials in a contact-free manner.  He will then present three recent studies from his group with a particular focus on interfacial electronic and ionic carrier dynamics in 2D materials and hybrids. Other recent research effort will be briefly discussed.

报告人简介

Prof. Hai Wang studied materials science at Zhejiang University and obtained his degree in 2009. Between 2009 and 2011, he finished a joint master program in nanoscience at University of Leuven (2009-2010) in Belgium and Delft University of Technology in the Netherlands (2010-2011), supported by the Erasmus Mundus fellowship. From 2012, Hai Wang started his PhD at Max Planck institute for polymer research (MPI-P) in Mainz with the support of a fellowship from MAINZ (graduate school of excellence, materials science in Mainz). After spending 1 year in the group of Mathias Kläui at University of Mainz as a postdoc, Hai started his independent research group “Nano-optoelectronic materials” in the Molecular Spectroscopy department at MPI-P in 2017. Employing time-resolved, ultrafast spectroscopies (THz spectroscopy, transient absorption etc.), the central theme of Hai’s current research lies in understanding fundamental charge carrier dynamics and low-energy excitations in solid-state low-dimensional materials and interfaces, relevant for energy and optoelectronic applications.
