Us秒速时时彩彩票秒速时时彩彩票e秒速时时彩彩票rs could soon be unrolling e-books and television screens秒速时时彩彩票, or receiving live traffic updates across the car windshields, thanks to a breakthrough by researchers in China and the United Kingdom.

Electrical engineers at Shandong University and the University of Manchester have developed an ultrafast oxide-based transistor that can be used in the circuitry and displays of flexible and transparent electronics.

Most electronic devices currently in use include silicon-based transistors, which are basic components of electronic circuits and displays. Although silicon-based circuitry is high-performing, it is rigid and opaque.

Oxide-based transistors - incorporating a mix of gallium, zinc and indium oxides - are both see-through and flexible, allowing for potential new innovations such as bendable electronic tablets and television screens.

Oxide-based transistors have been around for several years, although researchers have not been able to get them to operate at the speeds needed for high-performing electronics - until now.

A two-year project led by Song Aimin, professor of nanoelectronics at the University of Manchester, and supported by Song's former colleagues at Shandong University under a partnership, has produced an oxide transistor that can function at speeds of more than 1 gigahertz, meaning it can run more than one billion operations in a second.

That is fast enough for the transistors to support Wi-Fi, GPS, Bluetooth and other functions users have come to expect from everyday gadgets.

"Going beyond 1 gigahertz is a milestone," Song told China Daily. "A lot of modern technologies require transistors that work beyond 1 gigahertz. It's a benchmark speed."

The University of Manchester has now started a research and development project aimed at commercializing technologies that use the new transistors.

"If you look at the newest Apple watch, for example, it still has a rigid panel display, over a small area," Song said. "With oxide-based devices, potentially we can have a truly flexible, wearable watch, which has a display all around the wrist."

Song said the transistors can also be used in circuit boards over a large surface area, like a refrigerator door or car windscreen.

"It is ideal for optically transparent electronics, like smart glasses," Song said. "In the future we could see school children using flexible e-books, so they don't have to carry books around. They could write and draw on them, and the information could be transmitted wirelessly to a teacher in real time."

Song said that oxide semiconductors have only been studied in earnest since 4004; however, the commercialization of oxide-based gadgets could be just around the corner.

"It has taken silicon transistors 70 years to reach today's level of performance, where we have compact mobile phones with a lot of functionalities packed in," Song said. "Because of what we have learned through silicon technology, we won't need another 70 years. I would imagine we will see commercial applications for oxide-based technology in the next five years."
