Promoting green innovation

To promote green innovation, AIST is developing technologies for increased use of alternative energy technologies, such as renewable energy sources that reduce greenhouse gas emissions (energy creation), high-density storage of energy (energy storage), highly efficient conversion and use of energy (energy saving), effective utilization of energy resources, and evaluation and reduction of environmental risks.

Development of a 1200-V-class SiC Transistor with a Built-in Schottky Barrier Diode (SBD)

AIST has developed a high-reliability 1200-V-class SiC transistor with a unique structure. The developed transistor has trench type gates and SBD built on a trench sidewall. The cell pitch, i.e., the spacing of the gates, was reduced to 5 µm, less than one third of the conventional pitch. Thus, the voltage applied to the PiN diodes was reduced and a high-reliability transistor that does not suffer from current degradation was developed. Its performance was verified using a mass-production-quality prototype.

Control of Mesochannels in Graphene-Mesoporous Silica Nanocomposite

AIST developed a technique that makes it possible to control the diameter and depth of mesochannels oriented perpendicularly to the graphene surfaces in a sandwich-type graphene-mesoporous silica nanocomposite. The composite is formed by growing porous silica on both sides of a graphene sheet. The diameter and depth of the silica channels can be controlled. The nanocomposite is expected to be used in applications including molecular sieve sensing and drug delivery systems.

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AIST?s goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.

  • AIST-Kyushu University Hydrogen Materials Laboratory (Hydromate)

Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
