The phenomenon is via Cerenkov emission (CE) of acoustic phonons using intraband transitions proposed by Mensah et. al.,~\\cite{1} in Semiconductor Superlattices (SSL) and confirmed in ~\\cite{2}. From this, an asymmetric graph of $\\Gamma^{CNT}$ on $\\frac{V_d}{V_s}$ and $\\Omega\\tau$ were obtained where amplification ($\\Gamma_{amp}^{CNT}$) $>>$ absorption ($\\Gamma_{abs}^{CNT}$).
