Coherent control of 40-THz optical phonons in diamond using femtosecond optical pulses
Tetsuya Kimata, Kazuma Yoda, Hana Matsumoto +4
Coherent control is an optical technique to manipulate quantum states of matter. The coherent control of 40-THz optical phonons in diamond was demonstrated by using a pair of sub-1…
Coherent control theory and experiment of optical phonons in diamond
Hiroya Sasaki, Riho Tanaka, Yasuaki Okano +4
The coherent control of optical phonons has been experimentally demonstrated in various physical systems. While the transient dynamics for optical phonons can be explained by pheno…
Photon correlation in GaAs self-assembled quantum dots
T. Kuroda, M. Abbarchi, T. Mano +11
We report on photon coincidence measurement in a single GaAs self-assembled quantum dot (QD) using a pulsed excitation light source. At low excitation, when a neutral exciton line…
Area-Efficient Selective Multi-Threshold CMOS Design Methodology for Standby Leakage Power Reduction
Takeshi Kitahara, Naoyuki Kawabe, Fimihiro Minami +2
This paper presents a design flow for an improved selective multi-threshold(Selective-MT) circuit. The Selective-MT circuit is improved so that plural MT-cells can share one switch…
Self-assembly of laterally aligned GaAs quantum dot pairs
M. Yamagiwa, T. Mano, T. Kuroda +5
We report the fabrication of self-assembled, strain-free GaAs/AlGaAs quantum dot pairs which are laterally aligned in the growth plane, utilizing the droplet epit…
Photo-induced spin dynamics in ferromagnetic semiconductor -(Ga,Mn)As
Y. Mitsumori, A. Oiwa, T. Slupinski +4
Spin dynamics in ferromagnetic -(Ga,Mn)As ( = 0.011, = 30 K) has been studied by carefully comparing the decay time of the photo-induced reflectivity change with the…
