Second-order overtone and combination modes in the LOLA region of acid treated double-walled carbon nanotubes.
نویسنده
چکیده
Moderate acid treatment of double-walled carbon nanotubes (DWCNTs) has given rise to two new experimentally observed second-order double resonant Raman scattering frequencies centered at 1901 cm(-1) and 1942 cm(-1), in the highly dispersive LOLA region. These LOLA overtones and combination modes have been predicted by double resonance theory for two phonons associated with the K- and Gamma-points, respectively.
