Description
Low dimensional materials (1D and 2D) are promising candidates as building blocks of future electronics and optoelectronics. Controllable bandgap, strong light-matter interaction, sub-nanometer thickness, and high carrier mobility are among their favorable properties for electronic and optical applications. Comprehensive characterization of these materials is a crucial learning step toward their reliable incorporation in devices. In this work, we will discuss how temperature-dependent, multiwavelength excitation Raman spectroscopy could be effectively used to probe the interaction between the 1D graphene nanoribbons and various substrates (metal, oxides, semiconductors), including the effects on the phonon-carrier interaction, which are crucial for the device performance.
