Akira Endoh of Fujitsu Laboratories in Atsugi, Japan, rates the advance as an important step toward the realization of the terahertz transistor
In standard transistors
, electricity travels horizontally, so shortening the path requires that the transistor
be made thinner -- an increasingly difficult task with diminishing returns using today's chip manufacturing techniques.
The method that the researchers used to deposit the transistors
on plastic isn't amenable to large-scale manufacturing, says Tobin Marks of Northwestern University in Evanston, Ill.
Beyond manipulating them individually, a slow and tedious process, there has been no practical way to separate the metallic and semiconducting nanotubes -- a roadblock in using carbon nanotubes to build transistors
have long served as the building blocks of microelectronics.
That's because structural defects invariably riddle the thin crystalline films required for making transistors
or other devices.
One percent strain is a huge strain," he says, and it's enough to yield a 5 to 20 percent increase in transistor

Researchers have discovered that the transistor
, long the star of electronics, has a yet-untapped talent--emitting light.
SAN FRANCISCO -- RFMD(R) (Nasdaq: RFMD), a global leader in the design and manufacture of high-performance radio systems and solutions for applications that drive mobile communications, today introduced a family of Gallium Nitride (GaN) High Electron Mobility Transistor
(HEMT) high-power transistors
and is sampling to top-tier cellular infrastructure and WiMAX base station customers.
Unlike conventional transistor
fabrication, which takes place at elevated temperatures and requires high precision and ultraclean conditions, making fiber transistors
is "totally compatible with the weaving process," says Lee.
Intel's research and development involving new types of transistors
has resulted in further development of a tri-gate (3-D) transistor
for high-volume manufacturing.
In the half-century since the transistor
was invented, this workhorse component of almost every electronic device has shrunk from the size of a pencil eraser to smaller than a bacterium.
This mobility is one of the world's best - equal to amorphous-silicon, the most popular inorganic transistor
In a transistor
, electrons scurry along a channel whose length partly determines the device's speed.
