New Tech : Prolonged Power In Computers And Smartphones Post Posted: Mon Sep 29, 2014 1:02 pm

New inventions which made almost all iphone and computer users happy. Scientists have developed a new technology that could lead to gen next wearable computers with self-contained power sources and smartphones that do not die even after hours of heavy use.

By tapping into the power of a single electron to control energy consumption inside transistors could reduce energy consumption in mobile devices and computers, which are at the core of most modern electronic systems.

Researchers from the Erik Jonson School of Engineering and Computer Science at the University of Texas at Dallas, a part of the new technology, found that by adding a specific atomic thin film layer 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 and the steep devices use less voltage but still have a strong signal.

Dr Jiyoung Kim, professor of materials science and an author of the paper said, "The whole semiconductor 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."

"Our device is one solution to make this happen," said Kim.

The most energy-efficient way to transmit signals in electronic devices are tapping into the unique and subtle behavior of a single electron.

Moreover, as the signal is so small, it can be easily diluted by thermal noises at room temperature.

To verify this quantum signal, engineers and scientists who build electronic devices typically use external cooling techniques to compensate for the thermal energy in the electron environment.

The filter created by researchers is one route to effectively filter out the thermal noise.

Dr Kyeongjae "KJ" Cho, professor of materials science and engineering and physics and an author of the paper said that transistors made from this filtering technique could revolutionize the semiconductor industry.

Cho said, "Having to cool the thermal spread in modern transistors limits how small consumer electronics can be made."

"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 Cho.

We know that devices such as a smartphone or a tablet computes requires electrical power for operation. While, reducing operating voltage would mean longer shelf lives for these products and others.

Researchers said that lower power devices could mean computers worn with or on top of clothing that would not require an outside power source, among other things.

To create this technology, researchers added a chromium oxide thin film onto the device. That layer, at room temperature, filtered the cooler, stable electrons and provided stability to the device.
