Silicon is a common material for making computer chips. Recently, the Australian National University (ANU) and researchers at the University College London have collaborated to create laser-induced microscopic explosions on silicon, creating a variety of exotic new materials. Researchers believe that this new technology is expected to bring more simplified innovation and manufacturing processes to the field of superconducting, high-efficiency solar cells and light sensors.
The research director and ANU laser physicist Andre Rhodes said: "We have created two new crystal arrangements, or phases, with silicon. It seems that we can make four more. According to theoretical predictions, these The electronic properties of the material are very interesting, such as variable band gaps, proper doping may become superconductors, etc."
According to a report by the physicist organization network on June 29, the research team focused the laser on the silicon buried under the silicon dioxide layer, which can reliably blow up small pits on the solid silicon, which will generate extreme high voltage around the explosion point. , thus forming a new phase. The new phase structure is complex and it took the research team a year to understand it.
Professor Jim William of the ANU Electronic Materials Engineering Group said that they combined electron diffraction patterns and structural predictions and found that in the crystal structure of these new materials, the atoms are repeatedly arranged in 12, 16 or 32 numbers. “Micro-explosions turn the otherwise simple silicon structure into an extremely complex structure, which may bring them rare, unexpected properties.â€
Eugene Gamal, a professor at the ANU Institute of Physics and Engineering, said that these complex phases are usually unstable, but because of their small size, new materials can cool and solidify quickly before they deteriorate. Currently, these new crystal structures can be stored for more than one year.
Traditionally, the creation of new materials has to be done by micro-diamond anvils or extruded materials, and the ultra-short laser micro-explosion produces many times more pressure than the diamond anvil.
The research team's new approach is expected to make these special materials cheaper and easier to manufacture on a large scale. "We can reliably create thousands of micrometer-sized modification zones on ordinary silicon materials in a second," said Judy Bradby, Ph.D., of the ANU Institute of Physics and Engineering. "The semiconductor industry is worth dozens of dollars." With billions of dollars, some silicon atoms may have a significant impact even if they have only minor changes in their proper positions."
Some people say that the advancement of science is the progress of materials. The organization, nature, and function of materials have always influenced the development of science. This time, scientists from Australia and the United Kingdom produced this new material in a peculiar way, let us once again see the power of “destruction†– no one thought that the spark from an explosion could make The inconspicuous silicon material has a new vitality. According to the theory of cosmic explosion, "destruction" has always been creative. When the routine is broken, the original order will be subverted, leaving us with a bunch of mess, and maybe there are scientific discoveries that change the world.
Furniture Concealed Flush Handles
Furniture Concealed Flush Handles have been traditionally intended for Furniture Cabinet due to the need for Cabinet to pull or sliding back into a pocket, thus precluding the use of a knobs that protrudes from the face of the panel. Our Furniture Concealed Flush Pull Handles can fit for any type of decor of the house.
