    • Probing low-density carriers in a single atomic layer using terahertz parallel-plate waveguides 

      Razanoelina, Manjakavahoaka; Bagsican, Filchito Renee; Kawayama, Iwao; Zhang, Xiang; Ma, Lulu; Murakami, Hironaru; Vajtai, Robert; Ajayan, Pulickel M.; Kono, Junichiro; Tonouchi, Masayoshi (2016)
      As novel classes of two-dimensional (2D) materials and heterostructures continue to emerge at an increasing pace, methods are being sought for elucidating their electronic properties rapidly, non-destructively, and ...
    • Terahertz and Infrared Spectroscopy of Gated Large-Area Graphene 

      Ren, Lei; Zhang, Qi; Yao, Jun; Sun, Zhengzong; Kaneko, Ryosuke; Yan, Zheng; Nanot, Sébastien L.; Jin, Zhong; Kawayama, Iwao; Tonouchi, Masayoshi; Tour, James M.; Kono, Junichiro (2012)
      We have fabricated a centimeter-size single-layer graphene device with a gate electrode, which can modulate the transmission of terahertz and infrared waves. Using time-domain terahertz spectroscopy and Fourier-transform ...
    • Terahertz Dynamics of Quantum-Confined Electrons in Carbon Nanomaterials 

      Ren, Lei; Zhang, Qi; Nanot, Sébastien; Kawayama, Iwao; Tonouchi, Masayoshi; Kono, Junichiro (2012)
      Low-dimensional carbon nanostructures, such as single-wall carbon nanotubes (SWCNTs) and graphene, offer new opportunities for terahertz science and technology. Being zero-gap systems with a linear, photon-like energy ...
