Non-adiabatic Kohn-anomaly in a doped graphene monolayer
Michele Lazzeri, Francesco Mauri
We compute, from first-principles, the frequency of the E2g, Gamma phonon (Raman G-band) of graphene, as a function of the charge doping. Calculations are done using i) the adiabat…

Optical Phonons in Carbon Nanotubes: Kohn Anomalies, Peierls Distortions and Dynamic Effects
Stefano Piscanec, Michele Lazzeri, John Robertson +2
We present a detailed study of the vibrational properties of Single Wall Carbon Nanotubes (SWNTs). The phonon dispersions of SWNTs are strongly shaped by the effects of electron-ph…
