Characterizing Building Blocks for Optoelectronic Devices Based on Two-Dimensional Materials by Resonant Raman Spectroscopy

As is known, TMD, hBN and graphene have become essential building blocks in heterostructure-based devices. The identification of layer numbers and interlayer coupling of building blocks and the good interfacial coupling between different building blocks is essential for the device performance and property exploration. In this talk, I will discuss how to characterize building blocks for optoelectronic devices based on two-dimensional materials by resonant Raman spectroscopy, including layer number, interlayer coupling, interfacial coupling and electron-phonon coupling.
