NanoJapan: International Research Experience for Undergraduates Program
As the fields of science and engineering become increasing international there is a pressing need for the development of research and education programs to produce globally aware scientists and engineers. This PIRE renewal award supports the expansion of a unique interdisciplinary U.S.-Japan research and education partnership focused on terahertz (THz) dynamics in nanostructures. The U.S. and Japan are global leaders in both THz research and nanotechnology, and stimulating cooperation is critical to further advance THz science and develop commercial products from new ideas in the lab. The strong educational portfolio of this project focuses on cultivating interest in nanotechnology among young U.S. undergraduate students, especially those from underrepresented groups, and encouraging such students to pursue graduate study and academic research in the physical sciences. The NanoJapan International Research Experience for Undergraduates (IREU) Program is the lead educational initiative of this center. Recognized as a model for international education programs for science and engineering students, NanoJapan provides U.S. undergraduates with structured research opportunities in Japanese university laboratories with Japanese mentors. The TeraNano PIRE Center is supported by an NSF-PIRE Grant (OISE #0968405) and co-funded by the Office of International Science and Engineering, the Division of Electrical, Communications, and Cyber Systems, and the Division of Materials Research.

Excitonic effects on coherent phonon dynamics in single-wall carbon nanotubes
(2013)We discuss how excitons can affect the generation of coherent radial breathing modes in the ultrafast spectroscopy of single-wall carbon nanotubes. Photoexcited excitons can be localized spatially and give rise to a spatially distributed driving force in real space which involves many phonon wave vectors of the exciton-phonon interaction. The equation ... -
Collective antenna effects in the terahertz and infrared response of highly aligned carbon nanotube arrays
(2013)We study macroscopically aligned single-wall carbon nanotube arrays with uniform lengths via polarization-dependent terahertz and infrared transmission spectroscopy. Polarization anisotropy is extreme at frequencies less than ∼100 cm−1 with no sign of attenuation when the polarization is perpendicular to the alignment direction. The attenuation for ... -
Photoluminescence sidebands of carbon nanotubes below the bright singlet excitonic levels
(2009)We performed detailed photoluminescence (PL) spectroscopy studies of three different types of single-walled carbon nanotubes (SWNTs) by using samples that contain essentially only one chiral type of SWNT, (6,5), (7,5), or (10,5). The observed PL spectra unambiguously show the existence of an emission sideband at ∼140 meV below the lowest singlet ... -
GR-FET application for high-frequency detection device
(2013)A small forbidden gap matched to low-energy photons (meV) and a quasi-Dirac electron system are both definitive characteristics of bilayer graphene (GR) that has gained it considerable interest in realizing a broadly tunable sensor for application in the microwave region around gigahertz (GHz) and terahertz (THz) regimes. In this work, a systematic ... -
NanoJapan-International research experience for undergraduates program: Fostering U.S.-Japan research collaborations in terahertz science and technology of nanostructures
(2014-09-15)The international nature of science and engineering research demands that students have the skillsets necessary to collaborate internationally. However, limited options exist for science and engineering undergraduates who want to pursue research abroad. The NanoJapan International Research Experience for Undergraduates Program is an innovative response ... -
NanoJapan International Research Experience for Undergraduates: Preparing Globally Engaged Science and Engineers
(2013)The NanoJapan: International Research Experience for Undergraduates Program, established by a National Science Foundation Partnerships for International Research and Education (NSF-PIRE) grant in 2006, is a twelve-week summer program through which twelve freshman and sophomore physics and engineering students from U.S. universities complete research ... -
Rice University NanoJapan Program: Connecting US Undergraduates with Leading Japanese Nanotechnology Research Laboratories: National Science Foundation, Tokyo Regional Office
(2008-04-17)National Science Foundation, Tokyo Regional Office: Special Scientific Report #08-01. As international partnerships are becoming increasingly indispensible to solving major science and engineering problems, U.S. researchers and educators must be able to operate effectively in teams comprised of partners from different nations and cultural backgrounds. ... -
Imaging molecular adsorption and desorption dynamics on graphene using terahertz emission spectroscopy
(2014)Being an atomically thin material, graphene is known to be extremely susceptible to its environment, including defects and phonons in the substrate on which it is placed as well as gas molecules that surround it. Thus, any device design using graphene has to take into consideration all surrounding components, and device performance needs to be evaluated ... -
Macroscopic Ensembles of Aligned Carbon Nanotubes in Bubble Imprints Studied by Polarized Raman Microscopy
(2014)We study the alignment of single-wall carbon nanotubes (SWCNTs) in bubble imprints through polarized Raman microscopy. A hemispherical bubble containing SWCNTs is pressed against a glass substrate, resulting in an imprint of the bubble membrane with a coffee ring on the substrate. We find that macroscopic ensembles of aligned SWCNTs are obtained in ...
