The Advanced Electronic Materials Center (Managing Director: Toyohiro Chikyo) of the National Institute for Materials Science (President: Sukekatsu Ushioda), in joint work with Chiba University, Tokyo Institute of Technology, Nagoya University, the University of Tsukuba, Waseda University, and JST-CREST, developed a new electrode formation method for realization of future nano devices.
With Si semiconductors, a good metal/Si bond had been realized by doping the Si side in order to achieve an electrode/Si bond with a low contact resistance value.
However, with miniaturization of devices, deviations in the positions and the concentration of dopants added to the Si side began to affect the metal/Si interface, and it had become impossible to realize a stable electrode structure.
Subsequently, with further miniaturization of the junction region in Si devices, there was a tendency in structural design toward 3-dimensional devices using Si wiring. However, until now, there was no method of forming stable electrodes, and various problems also arose, such as large contact resistance, etc. The results of this research provide a revolutionary method which solves the problems encountered to date.
In integrated circuits and future nano devices, an understanding of the formation process of materials in nano spaces and the properties of those materials from the fundamental mechanism will contribute to solving essential problems. The results of the present research were demonstrated for the first time through collaboration by a large number of research institutions and researchers with various specialties.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
