By breaking the 3-nm process limit of the semiconductor, the scientists successfully developed the 0.7nm tungsten diselenide diode
It is reported that a few days ago, scientists successfully developed 0.7nm tungsten selenide diode, which means that human beings have finally broken the limit of semiconductor 3nm process, and made a small step forward in the development of semiconductor technology! Why do you say that? You may be keen on semiconductors, as you know, the process of semiconductors is in a period of rapid improvement with the development of smartphones, from 28nm, 16nm, 10nm, 7nm, 5nm to 3nm. However, in this process, the miniaturization process of semiconductor process is also slowed down by the gradual failure of Mooreundefineds law. What is Mooreundefineds Law? This was proposed in 1965 by Gordon Moore, one of Intelundefineds founders, that when prices remain unchanged, the number of components that can be accommodated in semiconductor chips will double in about two years, and their performance will improve year-on-year. Why is it on the premise that the price remains the same? There is no doubt about this. Because, from the point of view of the public, of course, it is hoped to buy more cost-effective mobile phones. If the price of semiconductors increases in geometry due to technological factors, the price of mobile phones will naturally rise, of course, this situation does not exist, because its promotion and application is not practical. So, what exactly is this tungsten selenide (WSe2)? These tungsten selenide, like graphene, are two-dimensional nanomaterials, which have many unique physical and chemical properties and are considered to be revolutionary in many fields such as computer and communication. To a lesser extent, tungsten diselenide, a transition metal disulfide compound (TMDs), can exhibit excellent semiconductor transmission characteristics in the thickness of the monoatomic layer (about 0.7nm). Compared with the previous traditional silicon semiconductor materials, it has exceeded the process limit of 3nm in thickness; in application, it can fully meet the needs of the next generation integrated circuit-thinner, smaller and faster. Of course, scientists are also interested in other two-dimensional nanomaterials with unique physical and chemical properties and great application value, such as tungsten trioxide, Mo _ 2O _ 3, titanium dioxide, zinc oxide and so on in transition metal oxides. In fact, so far, human research on two-dimensional nanomaterials has not been particularly in-depth. I hope our researchers, our little pride, will continue to work hard to develop new two-dimensional nanomaterials and discover their great potential value. It is believed that in the near future, two-dimensional nanomaterials will be widely used not only in mobile phone semiconductor chips, but also in catalysis, energy storage, sensors, solar cells and many other fields.
