    • Asymmetric excitation profiles in the resonance Raman response of armchair carbon nanotubes 

      Hároz, Erik H.; Duque, Juan G.; Barros, Eduardo B.; Telg, Hagen; Simpson, Jeffrey R.; Walker, Angela R. Hight; Khripin, Constantine Y.; Fagan, Jeffrey A.; Tu, Xiaomin; Zheng, Ming; Kono, Junichiro; Doorn, Stephen K. (2015)
      We performed tunable resonance Raman spectroscopy on samples highly enriched in the (5,5), (6,6), (7,7), and (8,8) armchair structures of metallic single-wall carbon nanotubes. We present Raman excitation profiles (REPs) ...
    • Diameter dependence of TO phonon frequencies and the Kohn anomaly in armchair single-wall carbon nanotubes 

      Telg, Hagen; Hároz, Erik H.; Duque, Juan G.; Tu, Xiaomin; Khripin, Constantine Y.; Fagan, Jeffrey A.; Zheng, Ming; Kono, Junichiro; Doorn, Stephen K. (2014)
      We present resonant Raman scattering experiments on nanotube samples enriched in metallic armchair single-wall carbon nanotubes (SWCNTs). We establish the transverse optical (ATO) phonon frequency for the (5,5) through ...
