Raman measurement is carried out to understand Vth shift in single-layer graphene field-effect transistors (GFETs). The G (2D) peak shift in Raman spectra is correlated to the corresponding ΔVth during stress and recovery phases. A blue (red) shift of G and 2D peaks is seen during stress (recovery)...
