World First Observation of Instantaneous Power Generation in Solar Cells
Industry is working expeditiously toward improving conversion efficiency in solar cells to make its use wide spread, an important key in resolving the energy problems of the future. It is said that if the solar energy could be converted completely, the world’s annual energy consumption could be met in as little as one hour. In recognition of this tend, Dainippon Screen and Osaka University have been continuing joint research on terahertz wave detection/analysis technology for solar cells and for the first time in the world succeeded to observe an instantaneous electrical generation of a solar cell for just one trillionth of a second.

World’s Fastest Wireless Transmission of 40 Gigabits per second
Group of Japanese researchers at NICT (National Institute of Information and Communication Technology) with collaboration with Osaka University have succeeded to achieve world’s record of 40 gigabits/s wireless transmission, which is 130 times faster than commercially available Wi-Fi technologies. The new transmission speed is capable of transmitting 32 gigabytes of data just in 6 seconds. The new record beats the previously set record of 27 Gbps. Read more
Development of Novel Transistor capable of performing both Logic and Memory Functions paving the way for realization of Instant-On PCs
Group of Researchers at National Institute for Materials Science (NIMS)headed by Dr. Tsuyoshi Hasegawa, in a joint research with Graduate School of Science of Osaka University headed by Prof. Takuji Ogawa, Graduate School of Engineering of headed by Prof. Shu Yamaguchi and the University of Tokyo has successfully developed a novel transistor, referred to as “atom transistor” capable of performing both logic as well as memory functions with power consumption that is 1/,1000,000 of the conventional devices paving the way for development of instant-on personal computers as well as other electronic equipment. Contrary to the conventional transistors that control the movement of electrons within the semiconductor, the newly developed “atom transistor” works by transferring a very small amount of metal atoms in an insulator, bearing a higher resistance than a semiconductor, as the base material.
