S. Korean scientists develop world`s first operational spin transistor
By Lee Joon-seung
SEOUL, Sept. 18 (Yonhap) -- South Korean scientists on Friday said they have
developed the world's first functioning spin transistor that can be used to make
next generation computers and information technology (IT) devices.
The team led by Chang Joon-yeon at state-run Korea Institute of Science and
Technology (KIST) said the prototype is noteworthy, because it effectively showed
the viability of a number of concepts related to spin transistors. The
breakthrough has been published in the latest issue of Science magazine.
"Researchers in the United States, Japan and Europe have demonstrated various
technologies that go into the making of a spin transistors, but none have
actually built one," the principle scientist in charge of development said.
In the past, engineers managed to create a "spin state" of electrons that have
been further upgraded by the KIST team who have developed the knowhow to control
the spin generated. Controlling the spin is vital to make commercially applicable
devices.
Spin transistors, also called spin field effect transistors, were first
conceptualized in the 1990s and is viewed as the next level of development of the
conventional complementary metal-oxide semiconductor transistors.
If the technology is fully perfected, it can create computers, IT devices, and
arithmetic logic units that can store more data in far less space and use less
power. A major advantage of the device is that spin transistors can operate
without an electric current, saving energy.
"In the long run, spin transistors could help create computers that do not
require the timely booting process, and memory devices and central processing
units merged into a single chip," Chang said. He added that while the prototype
cannot operate at ordinary room temperatures at present, work is underway to
perfect this technology in the coming year.
"We expect the technology to be available to get the transistors to operate in
room temperatures in 7-10 years," the scientist said.
KIST spent more than 10 billion won (US$8.3 million) since 2002 to develop the
transistor so far, and hasapplied for patents in the United States, Japan and
other countries.
