Coal will be able to replace silicon as the King of the next generation semiconductor

　　According to foreign media reports, Graphene is the most typical representative of thin film electronics, but says the current King of the semiconductor material, that belong to non-silicon, but from the MIT scientists will soon be able to squeeze it down. Recently, the MIT research team using coal to produce thin film electronics for the first time. Research team points out that this material is cheap and abundant resources, it can be used in electronic equipment, solar panels and batteries to find very good prospects.

　　According to composition, age and level of compression, coals are divided into four categories, namely half lignite, anthracite, bituminous coal, anthracite coal. Research team the four types of coal are made of thin film electronics and anthracite is determined by comparison is the most suitable raw materials for manufacturing thin-film electronic components.

　　First of all, scientists anthracite smash, and then place it in the solution, after using similar to Graphene silicon or thin film electronics manufacturing method the solution evenly deposited on the substrate. But unlike Silicon is that purity of coal does not need to be refined to 99%, but only to crush the General form, which greatly reduces the difficulty of the manufacturing process. Hello Kitty case

　　Although coal is one of the most abundant resources that are used, but most of the time people just use it as a fuel, researchers also focus less on its electronic and optical properties in the field of electronics applications.

　　Now, coal for MIT research team has created an electronic heating element, it can be for biomedical implants or auto defrost and other equipment for use. And the researchers also found that, by regulating the temperature the components, electronic and optical properties of coal can fully satisfy the specific number.

　　In addition, the researchers said they found was only the beginning, because there are four categories of coal, so they think each other's differences but also develop more functionality.

　　MIT Department of materials science and Engineering Professor Jeffrey Grossman says, the biggest advantage of new materials and its low cost. In addition, or Graphene and Silicon applications in electronic semiconductor compared to coal thin film manufacturing process is much simpler, because its purity is not as high as the former. iphone 6 Plus Hello Kitty case
