New York: A new technology to
control energy consumption inside
transistors could pave the way for a
smartphone that does not die after a
few hours of heavy use, says a study.
This technology taps into the power
of a single electron to control energy
consumption inside transistors.
"We devised a technique to cool the
electrons internally - allowing
reduction in operating voltage - so
that we can create even smaller,
more power-efficient devices," said
study co-author Kyeongjae Cho,
professor at the University of Texas,
Dallas.
Each time a device such as a
smartphone or a tablet computes, it
requires electrical power for
operation.
Reducing operating voltage would
mean longer shelf lives for these
products and others.
The researchers found that when a
specific atomic thin film layer was
added to a transistor, the layer acted
as a filter for the energy that passed
through it at room temperature.
The signal that resulted from the
device was six to seven times steeper
than that of traditional devices.
Steep
devices use less voltage but still have
a strong signal.
"The whole semi-conductor industry
is looking for steep devices because
they are key to having small,
powerful, mobile devices with many
functions that operate quickly
without spending a lot of battery
power," said co-author Jiyoung Kim,
a professor at the University of
Texas, Dallas in the US.
"Our device is one solution to make
this happen," Kim added.
The study appeared online in the
journal Nature Communications.
