Topological meaning of Z$_2$ numbers in time reversal invariant systems (2008)

Fukui, T., Fujiwara, T., Hatsugai, Y.

We show that the Z$_2$ invariant, which classifies the topological properties of time reversal invariant insulators, has deep relationship with the global anomaly. Although the second Chern number is...

Terahertz ultrasonic generation and detection in GaAs/AlGaAs quantum wells (2005)

Tachizaki, T., Matsuda, O., Fukui, T., Baumberg, J.J., Wright, O.B.

High frequency ultrasonic pulse generation and detection are investigated in a sample with three embedded GaAs/Al0.3Ga0.7As quantum wells by means of ultrashort optical pulses. The experimental...

Acoustic phonon generation and detection in GaAs/Al_{0.3}Ga_{0.7}As quantum wells with picosecond laser pulses (2005)

Matsuda, O., Tachizaki, T., Fukui, T., Baumberg, J. J., Wright, O. B.

Picosecond acoustic-phonon pulse generation and detection is investigated in a sample containing three GaAs/Al0.3Ga0.7As quantum wells of different thickness with an interferometric optical pump and...

Picosecond acoustics in semiconductor quantum wells (2005)

Matsuda, O., Tachizaki, T., Fukui, T., Baumberg, J.J., Wright, O.B.

Picosecond acoustic phonon pulses are generated with ultrashort laser pulses in a sample containing three GaAs-Al0.3Ga0.7As quantum wells of different thickness. The pump photon energy is tuned...

Catalyst-free selective-area MOVPE of semiconductor nanowires on (111)B oriented substrates (2004)

Motohisa, J., Noborisaka, J., Takeda, J., Inari, M., Fukui, T., 本久, 順一

We report on a catalyst-free approach for the growth of semiconductor nanowires which is attracting interest as building blocks for nanoscale electronics and circuits. Our approach is based on...

Growth of GaAs/AlGaAs hexagonal pillars on GaAs (1 1 1)B surfaces by selective-area MOVPE (2004)

Motohisa, J., Takeda, J., Inari, M., Noborisaka, J., Fukui, T., 本久, 順一

We report on the growth of GaAs and GaAs/AlGaAs heterostructured hexagonal pillar structures using selective area (SA) metalorganic vapor phase epitaxy (MOVPE). By performing growth on SiO2-masked (1...

Wavelength selective photoexcitation of picosecond acoustic-phonon pulses in a triple GaAs/Al0.3Ga0.7As quantum well structure (2002)

Matsuda, O., Ishii, I., Fukui, T., Baumberg, J.J., Wright, O.B.

Ultrashort coherent phonon-pulse generation and detection is investigated in a GaAs–Al0.3Ga0.7As quantum well structure containing three wells of different widths using an optical pump and probe...

Low temperature transport in dual-gated SETs fabricated by selective area metalorganic vapor phase epitaxy (2002)

Motohisa, J., Van Der Wiel, W. G., Elzerman, J. M., De Franceschi, S., Nakajima, F, Ogasawara, Y., ...

We describe transport measurements in a novel dual-gated single electron transistor based on a quantum dot (QD) fabricated by selective area growth of metalorganic vapor phase epitaxy. We observed,...

Engineered plant phosphorylase showing extraordinarily high affinity for various alpha-glucan molecules.

Mori, H., Tanizawa, K., Fukui, T.

alpha-Glucan phosphorylases are characterized by considerable difference in substrate specificities, even though the primary structures are well conserved among the enzymes from microorganisms,...

Probing the pyrophosphate-binding site in potato tuber UDP-glucose pyrophosphorylase with pyridoxal diphosphate.

Kazuta, Y., Tagaya, M., Tanizawa, K., Fukui, T.

Potato tuber UDP-glucose pyrophosphorylase (EC 2.7.7.9) catalyzes the reversible uridylyl transfer from UDP-glucose to MgPPi forming glucose 1-phosphate and MgUTP, according to an ordered bi-bi...

Survey of Japanese physicians' attitudes towards the care of adult patients in persistent vegetative state.

Asai, A, Maekawa, M, Akiguchi, I, Fukui, T, Miura, Y, Tanabe, N, ...

OBJECTIVES: Ethical issues have recently been raised regarding the appropriate care of patients in persistent vegetative state (PVS) in Japan. The purpose of our study is to study the attitudes and...
