Black lead Xi is a kind of exciting new-style material, because of its superior performance is known as ” of “ magical material. Black lead Xi gained wide attention 2010, award awarded Nobel physics to discover its researcher at that time. Black lead Xi has an atomic layer only thick, make its are become on weak data. Researcher points out, black lead Xi is to use laser “ to forging of ” . This will establish very strong three-dimensional structure with black lead Xi, OK and potential ground is used at making faster, more accurate mechanical equipment. Black lead Xi has the superior performance such as conductivity, diaphaneity and mechanical intensity. Because these are characteristic, black lead Xi will be applied extensively at the domain such as memory of the sources of energy, sensor or communication technology.

Researcher considered how to be passed expose black lead Xi will change its appearance and property in very short and powerful laser pulse. As a result of laser pulse, can become moulding of Xi of complete planar black lead three-dimensional structure normally. We say this kind of method forgings for optics, how to because it is similar to,forge three-dimensional appearance with the plate with will flat hammer. Use optics forgings the structure that makes counts hundredfold higher than the ply of black lead Xi, but very small still, so that they are stuck very easily on the hair, researcher says. Laser makes black lead Xi hardens 　 for example, the equipment that makes by black lead Xi is the different sensor that works through mechanical vibration. It is OK that people discovers optics forgings make black lead Xi hardens, make its bend not easily thereby. This is an interesting observation result, because the addition of flexural rigidity also can increase the oscillatory frequency of black lead Xi. Increase frequency, conversely, can raise the speed of equipment and precision. Use optics forgings, we can be created piece than not hardness of Xi of modified black lead is as high as 10 thousand the structure of times. For so weak to resembling data, this is record-breaking, researcher says. The result 　 that appearance is atomic measure change is considering to discover in the process, optics forgings the crystal lattice defect that can cause black lead Xi, namely structure of black lead Xi ruptures. Black lead Xi begins to rupture from random dot. The time that if black lead Xi is exposed,leaves in laser illuminate is enough long, the blemish that order state can form a line shape blemish or crackle. What these blemish bring about black lead Xi is local expand, bring about black lead Xi to expand thereby three-dimensional appearance. This research lets us how change the knowledge that had development to the appearance of black lead Xi and its attribute. The one big advantage of this method is, xi of got-up black lead does not need complex process or chemical processing, need laser only, researcher is summed up.
