Autor: Kazunori Kakehi, Yukio Yamaguchi, Shigeo Maruyama, Suguru Noda, Kei Hasegawa, Hisashi Sugime

Publikováno v: Journal of Nanoscience and Nanotechnology. 8:6123-6128

Our group recently reproduced the water-assisted growth method, so-called "super growth", of millimeter-thick single-walled carbon nanotube (SWNT) forests by using C2H4/ H2/ H2O/ Ar reactant gas and Fe/ Al2O3 catalyst. In this current work, a paramet

Individuals, grasses, and forests of single- and multi-walled carbon nanotubes grown by supported Co catalysts of different nominal thicknesses

Autor: Shigeo Maruyama, Yukio Yamaguchi, Kazunori Kakehi, Suguru Noda

Publikováno v: Applied Surface Science. 254:6710-6714

The relationships among the nominal thickness of Co catalyst, the structure of the catalyst particles, and the structure of carbon nanotubes (CNTs) growing from the catalyst during chemical vapor deposition were investigated. Various morphologies of

Growth Valley Dividing Single- and Multi-Walled Carbon Nanotubes: Combinatorial Study of Nominal Thickness of Co Catalyst

Autor: Yukio Yamaguchi, Kazunori Kakehi, Suguru Noda, Shigeo Maruyama

Publikováno v: Japanese Journal of Applied Physics. 47:1961-1965

The relationships among the nominal thickness of Co catalysts, the structure of the catalyst particles, and the structure of carbon nanotubes (CNTs) growing from the catalysts were investigated. A gradient thickness profile of Co was prepared using a

Supported Ni catalysts from nominal monolayer grow single-walled carbon nanotubes

Autor: Shigeo Maruyama, Shohei Chiashi, Kazunori Kakehi, Suguru Noda

Publikováno v: Chemical Physics Letters. 428:381-385

Fe, Co, and Ni are catalytically effective for growing single-walled carbon nanotubes (SWNTs). On substrates, however, Ni tends to yield only multi-walled carbon nanotubes. Because enhanced surface diffusion at the elevated growth temperature require

Suppression of crosstalk by using backside deep trench isolation for 1.12μm backside illuminated CMOS image sensor

Autor: Yusuke Kohyama, S. Uya, Hirofumi Yamashita, Kazunori Kakehi, Minami Takaaki, K. Eda, Yosuke Kitamura, Hisanori Aikawa, T. Yousyou, T. Asami, Y. Takegawa

Publikováno v: 2012 International Electron Devices Meeting.

1.12μm backside illuminated CMOS image sensor with backside deep trench isolation (DTI) has been demonstrated for the first time. DTI is fabricated on backside pixel surface after wafer bonding and grinding process. Backside DTI makes its layout sim

Millimeter-Thick Single-Walled Carbon Nanotube Forests: Hidden Role of Catalyst Support

Autor: Hisashi Sugime, Zhengyi Zhang, Shigeo Maruyama, Suguru Noda, Yukio Yamaguchi, Kazunori Kakehi, Kei Hasegawa

A parametric study of so-called "super growth" of single-walled carbon nanotubes(SWNTs) was done by using combinatorial libraries of iron/aluminum oxide catalysts. Millimeter-thick forests of nanotubes grew within 10 min, and those grown by using cat
