We examined the optoelectronic properties of atomically thin 1D van der Waals heterostructures comprising the single-walled carbon nanotubes wrapped by insulating BN layers and MoS2 outer layers (MoS2@BN@CNT). We will present the equilibrium properties of such materials (through optical absorption, Raman scattering, photoluminescence, FTIR and THz spectroscopy studies), and the dynamical properties of excitons and free charges (via optical pump-optical probe, and optical pump – THz probe spectroscopy).
