Autor: Hiroyuki Saito, Shotaro Baba, Yoshihiko Saito, Hiroshi Yamada-Kaneta, K. Mitsumoto, Terutaka Goto, Kazuhiko Kashima, Yuichi Nemoto, Mitsuhiro Akatsu, Kazuki Okabe

Publikováno v: ECS Transactions. 64:13-18

For the samples taken from the void region of the CZ silicon crystal grown with the same solidification condition and different thermal histories after the solidification, we measure the magnitude S of the elastic softening which is proportional to t

(Invited) Practical Method and Physics of Evaluation for Vacancy Concentration of Silicon Crystals by Measuring Low-Temperature Elastic Softening

Autor: Mitsuhiro Akatsu, Y. Nemoto, Shotaro Baba, Keisuke Mitsumoto, Kazuki Okabe, Hiroshi Yamada-Kaneta, Takashi Yanase, Yuta Nagai, Yasushi Ono, Terutaka Goto

Publikováno v: ECS Transactions. 33:63-72

The paper reports the recent progress of our research on the vacancies in boron-doped (B-doped) as-grown silicon crystals of commercial-base quality achieved by means of the low-temperature ultrasonic measurements. The paper also demonstrates how our

Visualization and Analyses of Jet Structures from a Cluster-Type Linear Aerospike Nozzle

Autor: Mashio Taniguchi, Tomohide Niimi, Kazuki Okabe, Hideo Mori, Yusuke Masai

Publikováno v: JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES. 52:235-240

Aerospike nozzles have been expected as a candidate for an engine of reusable space shuttles to respond to growing demand for rocket-launching and its cost reduction. In this study, the flow field structure in any cross sections around the linear-typ
