Nonlinear-
and Magneto-Optical Properties in Single-Walled Carbon
Nanotubes |
| |
Masao Ichida
(Lecturer, Konan University) |
| A single-walled carbon nanotube
can be regarded as a naturally grown quantum wire,
and it shows quasi one-dimmensional (1D) enectronic
structure. Depending on the fundamental structure,
a single-walled carbon nanotube can be either a
metal or a semiconductor. In this stydy, I investigate
1D electronic structures in single-walledcarbon
nanotubes. I will evaluate the possibility of nonlinear-
and magneto- optical material in single-walled carbon
nanotubes. |

Creation
of high performance gas storage materials by nanoprocessing
technology |
| |
Zheng-Ming Wang
(Researcher，Institute for Marine Resources and Environment，AIST) |
| Despite the preferable geometrical
structure for gas storage, research on nanoporous
materials with very thin walls has not been systematically
carried out. The objective of this research is to
create nanoporous materials ideal for gas storage
by physically and chemically functioning the layered
compound precursors with very thin walls via the
modern nanoprocessing technology such as intercalation,
soft chemical template method, etc. |

Control
and applications of novel spin properties found in semiconducting
nano structures |
| |
Takaaki Koga
(Associate Professor, Hokkaido University) |
| In this research project, I
plan to develop methodologies to control the spin
properties of conduction electrons in semiconducting
nanostructures with the aim of paving the way to
realizing future spintronics devices. In order to
reach this goal, I propose to make a positive use
of spin-orbit interaction effect that is related
to the lack of the structural inversion symmetry
of the pertinent electron systems. One application
of this effect is the realization of a non-magnetic
spin filter that can be made without using magnetic
materials. Other research plans include the studies
of spin precession and spin interference effects
in semiconducting nanostructures. |

Ferromagnet/semiconductor
hybrid devices using fully epitaxial ferromagnetic tunnel
junctions |

Satoshi Sugahara
(Research Associate,The University of Tokyo) |
| This project aims to develop
functional devices based on exotic magnetotransport
phenomena in fully epitaxial ferromagnet/semiconductor/ferromagnet
trilayer nanostructures with the atomically controlled
heterointerfaces. Novel spin-electronic device architectures
combining well-refined semiconductor technology
with the spin degree of freedom are explored. |

Artificial
manipulation of carrier spins in quantum dots |
| |
Atsushi Tackeuchi
(Professor, Waseda University) |
| An electronic spin may become
the new flexibility which can be operated artificially.
Especially, in quantum dots, since a spin is maintained
coherently during nanoseconds by 3-dimensional quantum
confinement effect, it may be applicable to quantum
memory or computing. This research aims at utilizing
this underdeveloped flexibility for quantum computing,
by investigating behavior of the spin and the spin
flip process due to the inter-dot interaction. |

Construction
of Strongly Correlated Electron Devices by Nano-scale
Functionally Harmonized Artificial Lattices |
| |
Hidekazu Tanaka
(Associate Professor, Osaka University) |
| Transition metal oxides exhibit
a rich variety of physical properties due to the
strong correlation among electrons. The aim of this
research is to construct the novel functional artificial
materials and devices, which enable us to control
ferromagnetism, colossal magnetoresistance, superconductivity,
or metal-insulator transition by light or electric
filed at room temperature. I will combine these
magnetic oxides with semiconductive oxides at nano-scale
in artificial lattices, and control the behavior
of the correlated electrons through the interface.

Coherent
manipulation of quantum dot states utilizing spatiotemporally
controlled light |
| |
Yasunori Toda
(Associate Professor, Hokkaido University) |
| In semiconductor quantum dots,
carrier-phonon interaction should be enhanced when
the energy separation of the discrete states matches
a phonon. This research aims at decoherence control
of carriers by means of the selectively and coherently
excited phonons in individual quantum dots. By using
carrier-phonon coherent coupling, new types of quantum
manipulation of 0-dimensional states will be expected.

Development
of a Novel Bioactive Material Made of an Inorganic-Organic
Composite with Cells |

Tsutomu Furuzono
(Division Head, National Cardiovascular Center Research
Institute) |
| Adhesive property for a long
term between an artificial material and a living
body", this is an important problem in all artificial
organs and an indispensable technique around an
artificial organ attached on a body. In this project,
I will develop a novel percutaneous device made
of the material in order to protect germ infection,
and achieve an early appearance of the device in
medical field. |

An
advanced low-energy electron diffraction method to determine
atomic arrangements of nano-materials |
| |
Seigi Mizuno
(Associate Professor, Kyushu University) |
| As the size of the nanometer-scale
materials becomes smaller and smaller, it becomes
important to determine atomic arrangements. The
goal of this study is to develop a low-energy electron
diffraction method for structure determination of
nano-materials. In order to achieve nanometer-scale
resolution, I will use scanning tunneling microscope
tips as a field emission gun. Detection of diffraction
patterns from the surface of small areas will make
it possible to analyze the atomic arrangements of
nano-materials. This method will be useful for creation
of new nano-materials. |

Superheterostructures
for nano-electronics and photonics |
| |
Masahiro Watanabe
(Associate Professor, Tokyo Institute
of Technology) |
| Heterostructures composed of
metal, insulator and semiconductor nanostructures
( super-hetero-nanocrystals ) are attractive material
for controlling electron waves in nanometer scale:
quantum confinement, resonant tunneling, and electron-photon
interaction like intersubband transition. In this
project, novel fabrication technique and physical
properties of super-hetero-nanocrystals are investigated
using fluorite based insulator and silicide metals
epitaxially grown on silicon substrate. |
