A research on high performance and low noise transistors spearheaded by assistant professor for manufacturing and industrial systems engineering, Suprem Das, in association with scientists at Purdue University, was lately posted in Physical Review Applied.
The research has showed nano/micro-scale transistors created of 2D dimensional atomic thin substances that display low noise and high performance. The machines can be a solution to precision sensing & innovating electronics and are less than 1/100th of the diameter of a human hair.
Many scientists all over the world are aiming on developing the next gen of transistors from atomic scale 2D substances such as molybdenum di-selenide. These substances have the potential since they display high performance transistor-action that might replace silicon electronics used nowadays. On the other hand, a couple of them are seeking at yet one more essential aspect: the intrinsic electronic noise in this new category of substances. Electronic noise is omnipresent to all circuits & devices and only gets worse when the substance turns out to be atomic thin.
On a related note, have you ever thought what if you could get a notification on your smartphone informing that the milk carton you bought is going to be out-of-date? Yes, this can soon be a reality. All thanks to the research team who have developed a printed transistor that consists of complete 2D nanomaterials. The researchers have utilized a standard printing methodology to merge graphene nanosheets, which would act as electrodes, with other 2 nanomaterials, boron nitride and tungsten diselenide as separator and channel to make an all nanosheet, all printed, functioning transistor.
As per the researchers, this fabrication of a new transistor has come up with new avenues for industries, such as pharmaceuticals and ICT, to cost-effectively print a crowd of electronic equipment from LEDs to solar cells with applications to next-generation banknote security and e-passports from interactive smart food and drug labels.
