Introduction and overview

Localised strain and doping of 2D materials

“…Several attempts have been taken to confine the laser into sub-diffraction limit and to enhance the scattering signals to the detectable level by generating a local plasmonics through localised light-metal interaction under surface-enhanced Raman spectroscopy (SERS) and tip-enhanced Raman spectroscopy (TERS) techniques. 94 Wrinkles are also observed in CVD graphene (Fig. 10c and d) due to its lower TEC than that of substrate and thus the lattice mismatch during the cooling process in fabrication.…”
