• ; nanobar; nanoring; terahertz emitter; Introduction The terahertz (THz) range of the electromagnetic waves, the range between microwaves and infrared (IR), is often discussed in reference to the “terahertz gap”, where “electronics meets optics”. The corresponding radiation, exhibiting properties common to

• longitudinal velocity of sound vL, one arrives at the estimate for γ in terms of nvm and L: Note that in GNB, L is the length of the nanobar, whereas in GNR, the median contour length π(R + r) should be taken instead (see Figure 3b), hence Taking into account the condition nvmΔEvm + hν ≈ 17.4 meV along with
