South Polytechnic uses graphene to cut off the high cost of LED lights

Nanjing University of Science and Technology recently released, the school has made progress in the development of new two-dimensional semiconductors, is expected to create new materials, greatly reducing the cost of LED lamp production, the research results have been published online in the top journal of chemical and materials, "German Applied Chemistry". It has been selected as a hot article by academic media such as Nature and NanoWerk. The LED lights that can be bought in the market are ten times higher than the ordinary lamps, so that the LED lights cannot enter the homes of the people. According to Zeng Haibo, director of the Institute of Nano-optoelectronic Materials, South China Institute of Technology, new materials such as graphene, which is widely used and low in cost, are very suitable for manufacturing information and energy devices including LEDs. However, the metallic and semi-metallic properties of these materials have become fatal. How to change the properties of these materials has become a bottleneck that is hard to overcome in the material science community. Manufacturing LED is only one aspect of the application of this new material. Zeng Haibo introduced that this material can also replace silicon and be applied to the manufacture of computers and mobile phone chips. Once applied, wearable electronic devices such as Google Glass and Smart Health Bracelets will not only perform well. It is leaps and bounds, and it will be lighter and smaller, and the price will be more close to the people.
