Quantum Optoelectronics And Plasmonics With Novel Van Der Waals Heterostructures
Abstract
Research objective: The compelling demand for higher-performance electronic, optoelectronicand energy harvesting devices with state-of-the-art functionalities is the driving force to buildnovel architectures based on innovative materials. The emerging van der Waals crystals,including graphene (semi-metal), hexagonal boron nitride (insulator), transition metaldichalcogenides (semiconductors), and various heterostructures formed from them, possessunique properties that are fundamentally different from conventional materials, providing newopportunities for next-generation nanoelectronic applications. The objective of the proposedresearch is to investigate the physical properties of charge, spin, thermal and plasmonicexcitations in these materials, in order to meet the immediate needs for cutting-edge devices withflexibility, low-power consumption and ultrafast operation speeds.Technical approaches: The proposed research includes two main approaches: first is the use ofstate-of-the-art nanofabrication techniques to fabricate van der Waals heterostructures withultraclean interfaces using a polymer-free layer assembly method; the second is to investigate theelectronic, spintronic, thermal and plasmonic behaviors of the fabricated structures by usingspatially, spectroscopically, temporally and light-polarization-resolved transport, photocurrentand plasmonic measurement techniques.
