Road to the Development of an Instant-on PC

01.02.2011
Development of novel transistor with combined logic and memory functions with power consumption reduced to one-millionth that of conventional devices.

A group headed by Dr. Tsuyoshi Hasegawa, a Principal Investigator at the International Center for Materials Nanoarchitectonics (MANA; Director-General: Masakazu Aono), National Institute for Materials Science (President: Sukekatsu Ushioda), in joint research with a research group under Prof. Takuji Ogawa of the Graduate School of Science, Osaka University, and a research group under Prof. Shu Yamaguchi of the Graduate School of Engineering, The University of Tokyo, succeeded in the development of a novel transistor, the gatom transistor,h which performs both logic and memory functions while reducing power consumption to 1 x 10-6 that of the conventional devices.

Logic elements which are capable of retaining their state (i.e., memory) will be indispensible for the development of instant-on personal computers (PC) and other electronic equipment. The development in this work is expected to accelerate the realization of these devices.

In contrast to conventional transistors, which control the movement of electrons in a semiconductor, the newly-developed gatom transistorh operates by transferring a very small amount of metal atoms in an insulator. By using an insulator, which has higher resistance than a semiconductor, as the base material, and realizing on/off states by transfer of a tiny amount metal atoms in this material, the new device achieves a high on/off ratio on the same level as conventional semiconductor transistors with extremely low power consumption. Furthermore, it was found that the gatom transistorh also operates as a memory element which retains states by control of the operating voltage range.

As non-volatile logic circuits, which reconfigure circuits corresponding to computational results, are able to retain their state even when the power supply is turned off, high expectations are placed on the developed device as a new type of computer circuit for realizing PCs with zero starting time. Conventionally, one glogic element with memoryh was formed by combining a logic element (transistor) and a memory element (memory). However, with the conventional devices, the power consumption required for memory is extremely high, and low power consumption, in which memory power requirements are greatly reduced, had been considered necessary for practical application. The gatom transistorh developed in this research reduces the power consumption required for memory to 1/1,000,000 that of the conventional technology. In addition, because it possesses both logic and memory functions, it is expected to contribute to the realization of neural computing systems.

This research was carried out as part of the research topic gDevelopment of Atom Transistorh (Research Representative: Tsuyoshi Hasegawa) in the research area gResearch of Innovative Material and Process for Creation of Next-generation Electronics Devicesh (Research Supervisor, Dr. Hisatsune Watanabe, President & CEO, Semiconductor Leading Edge Technologies, Inc.), Core Research of Evolutional Science & Technology, Team-based Basic Research (CREST) of the Japan Science and Technology Agency (JST). These results were published online by the scientific journal gApplied Physics Express (APEX)h on December 24, 2010.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
