A Nano-sheet Transistor Allows Continuous Control of Superconducting States [press release: Nov. 30, 2012]
Ever since its development in the early 1950s, a transistor, the fundamental building block of modern electronic, has never stopped its evolution of being faster and smaller,
a process that recently imminently demised by physical boundaries that limit the miniaturization. Researchers at QPEC, University of Tokyo and RIKEN developed a new type of transistor
on nano-sheets isolated from an abundant layered natural mineral. This nano device is offering a continuous control of a quantum state of matter, superconductivity,
paving ways for future electronic with new operation concepts.

A New Route to Dissipationless Electronics
Realization of a new type of magnetic phase in devices opens the door to electronics based on topologically non-trivial materials [press release: August 20, 2012]
A team of researchers at RIKEN and the University of Tokyo has demonstrated a new material that promises to eliminate loss in electrical power transmission.
The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized
less than a decade ago - a magnetic topological insulator.
Switching the state of matter
New transistor harnessing strong electron correlations enables electrical switching of the state of matter [press release: July 26, 2012]
Sixty years after the transistor began a technological revolution that transformed nearly every aspect of our daily lives, a new transistor brings innovations
that may help to do so again. Developed at RIKEN, the device uses the electrostatic accumulation of electrical charge on the surface of a strongly-correlated material
to trigger bulk switching of electronic state. Functional at room temperature and triggered by a potential of only 1 V, the switching mechanism provides a novel
building block for ultra low power devices, non-volatile memory and optical switches based on a new device concept.
Demonstration of “electronic ferroelectricity,”
a new principle underlying electric polarization in an organic ferroelectric [press release: June 1, 2012]

in collaboration with Sachio Horiuchi and his team at the National Institute of Advanced Industrial Science and Technology, Fumitaka Kagawa
(lecturer at the University of Tokyo), and Yoshinori Tokura (the University of Tokyo and Group director of Riken).
This press release was issued by KEK on June 1, 2012. Scientific paper was published in Physical Review Letters. (June 4, 2012)
