Silylene considered applications in the future of electronic components will exceed the graphene. Recently, composed of Italy and USA scientific research personnel team to create the world's first silylene transistor. The results will accelerate the silylene practical application process.
Silylene is a made of a single atom thick silicon materials, like graphene, has proven to be conductive performance is extraordinary, but the preparation process is very difficult. This transistor has enormous potential, for computer scientists
Say, silylenes is a more interesting than graphene materials. 7 years ago, a dream silylene also just theorists. Driven by the heat of the graphene, the researchers speculate, silicon atoms may form a similar surface. And if it
They can be used for the production of electronic products, the semiconductor industry silylene film will enable to achieve the ultimate dream of miniaturization.
At present, the research team plans to refining production process, in order to create a longer life expectancy in the short term
Silicon graphene transistors. Of which there are many difficulties to overcome, because silylene in real world use is very unstable, but scientists said: "this is a major breakthrough in manufacturing technology, low temperature and silylene original equipment manufacture or
For the first time. The researchers believe that the future of electronic components, the application of silicon alkenes can more easily than the graphene chip design, after all, most of them are based on silicon.
American Texas State University of nano materials
The researchers, involved in the production of the transistor Deji
Akinwande said that, although the performance of the device is still relatively common, service life also can only to gauge for minutes, but this concept has been highly concerned by confirmed. The first French Marseilles University materials scientists
Guy Le Lay agree with him. "No one expected to realize it in such a short period of time, after all, a completely non-existent materials manufacturing transistor can not be used." He said.
But in the experiment
There has been a huge challenge processing silylene chamber, this material can not be like graphene like that, the formation of bulk graphite, and tape from a solid block off. Replace sb. is, researchers by allowing the silicon atoms in really hot steam
Air chamber concentration to a piece of transparent silver block up to get it, this is a very complex process. And unlike the robust graphene, silylene alone in the air very unstable, it is difficult to put the thin surface plating to a more useful basis
The inner wall of the floor -- such as transistors. Because of this, until last year, some researchers have questioned the silylene whether there.
Into reality with the silylene transistor, the graphene is not suitable for making crystal
Knowledge body tube grow with each passing day. Graphene is possibly the world's highest conductivity material, but the lack of a key characteristics. The use of semiconductor and computer chips in different, it lacks bandgap -- electronic carrying current before
The energy must jump over hurdles. The band gap of semiconductor equipment can let off, the implementation of the "logical" operation.
By contrast, Si ene have band gaps. However, this transistor is still cannot be used for a mobile phone in the short term: because the silylene exposed 2 minutes or so will degenerate. However, this time is enough to detect its characteristics. If the silylene transistor with a layer of coating can prolong its service life. Akinwande has used PTFE help phosphorus vinyl film "survival" for months.
