As an Electronics Engineer, I know the importance of Moore’s law in technology and its advancement. From past few days, every scientist and engineer is taunting the long lasted law for losing its longevity in this era. But these researchers gave Moore’s law another chance by creating World’s Thinnest Transistor. Once again, the law stands after its first proposal in 1965.
Now I am going to tell more about the basics of Moore’s law and the thinnest transistor ever made in history. Starting with Moore’s law, In 1965 Moore proposed a theory according to which the overall processing power of computers will double every two years. Or in another way, the number of transistors on a integrated circuit will double after every two year. So to do that, you have to decrease the transistor size in half in the only two-year period without changing the size of IC.
People think what’s the profit of this law or its a mere prediction, but in a real sense, it has too much to offer for our technological community. It started like a simple prophecy then it became a goal for every scientist and engineer to compete with their predecessors’ work. The researchers are always thinking that their past generations have tried to follow this law without new technologies, so it’s their duty to follow Moore’s Law. But, everything has its ultimate limit as do Moore’s law.
But for now, Moore’s law is extended for two more years as these researchers Kibum Kang, Saien Xie, Lujie Huang, Yimo Han, Pinshane Y. Huang, Kin Fai Mak, Cheol-Joo Kim, David Muller and Jiwoong Park have done the impossible by yet creating ultrathin three atom thick transistor.
Now some information for the electronics guys: the world’s thinnest transistor is made using transition-metal dichalcogenides (TMD), which can form stable three-atom-thick monolayers. The ideal material for transistor making like Si and GaAs have already reached their limits, so these new transition metals like molybdenum disulfide and tungsten disulphide are the major part of this transistor.

“The electrical performance of our materials was comparable to that of reported results from single crystals of molybdenum disulfide, but instead of a tiny crystal, here we have a 4-inch (10-cm) wafer,” one of the team member, Jiwoong Park said about the device. The technique to grow the layer is new in the field as they are using metal–organic chemical vapour deposition(MOCVD) technique.
The process starts with two commercially available precursor compounds — diethylsulfide and a metal hexacarbonyl compound — mixed on a silicon wafer and baked at 550 degrees Celsius for 26 hours in the presence of hydrogen gas. The result was an array of 200 ultra-thin transistors with good electron mobility and only a few defects. Just two of them failed to conduct, leaving researchers with a 99 percent success rate – according to the Verge.
As a result, world’s thinnest transistor would bring wide benefits for applications in ultrathin and flexible electronics, photovoltaics and display technology. Also, the future possibilities are too extensive means will cover every aspect of our life. Now the challenge will be to develop and extend this technology according to consumer use. But for now, Moore’s law is safe and we all get an ultra-thin transistor, which can reduce the size of every electronic device and gadget in drastic manner. So be ready for finger size phones and palm sized laptops in near future thanks to the world’s thinnest transistor.
