Australian scientists successfully exploited only billionths of meters in diameter nanowires generate laser. They point out that the results of this study is a key step in the manufacture of future computer chips toward the road towards.
According to the Australian Broadcasting Corporation (ABC) reported that Australian scientists said future computer circuit manufacture in three dimensions, using light instead of electricity running. The reason for making this idea comes from a group of nanotechnology research scientist at the Australian National University obtained. They successfully exploited only billionths of meters in diameter nanowires generate laser. They point out that the results of this study is a key step in the manufacture of future computer chips toward the road towards.
The main author of research papers, doctoral Deh Australian National Ruff – Mosaic Wisner pointed manufactured using light computer circuit has many advantages. He said: “The light transmission is much faster than electronic means that we can create faster computers, smaller in size and more energy-efficient chips if we use nanowires and light, we can in three dimensions. manufacture of circuits, the use of light to transmit information between interconnected layers, thus creating a more compact, faster processors, “research paper published in” Nature -. on photonics “magazine.
The researchers pointed out that this miniature laser can also be used to make ultra-sensitive optical sensor and near-field optical microscope. Major breakthrough in the Australian National University researchers have made is to find a way to use GaAs manufacturing miniature circuit approach. This circuit can operate at room temperature. Course of the study, they will tiny gold particles deposited on a surface, then in the case of the presence of a gas containing gallium and arsenic, gold particles were heated to 750 degrees Celsius.
Study co-author 苏德哈 – Dr. Mocha Patty pointed out that in this environment, gallium and arsenic react to form solid crystals can guide light line. She said: “relative to the air, the gallium arsenide with a high refractive index, can guide light through, the end of the nanowire acts as a mirror.” Isner said mosaic nanowires using such computer chip manufacturing still need several years of research and development in order to become a reality. Our research shows that nanowires can work at room temperature, which is an important research results. He said: “We need to conduct extensive research, hoping to achieve this goal in 10 years.
