Super performing electrons in a new platform. The scientists and technologists of the University of Wisconsin-Madison have successfully created the functionally most flexible transistor available in the world. They have been successful in doing this in a very simple and less costly method which is fast and can easily be done in mass produce commercially.
In the modern world of connectivity, this can pave a new path, to sum up, new products smartly and wirelessly. These products can be large or small. For example like wireless sensors for anyone to measure curvature length breadth etc.
Transistors and the process
In the field of modern electronics, transistors are considered the basic. The scientists have done advancement on a nearly twenty-year-old standard BiCMOS or a bipolar complementary metal oxide semiconductor.
They used a very thin film of this, which is combined with two very different technologies. It combines the speed and high current with the low power dissipation in the forms of heat and energy wastage. And all these are done on one surface.
As a result of this, a mixed kind of signal is generated. They are analog and digital both. This is the concept of modern smartphone technology.
Zhengiang Ma is the lead scientist of this project. He is the professor of electrical and computer engineering at the University of Wisconsin-Madison. He said that the standards in the industry are good.
It is now that we can do the same with this newly invented transistor and it can even bend. The report of his team has been published in the 27th September edition of the journal Flexible Electronics.
Conventional process versus new method
In the conventional method, it takes months to make a BiCMOS. This includes many high-temperature processes and very sensitive applications. It is so sensitive to temperature that even slightest change can be a huge mistake.
Using a unique process Prof. M and his team has developed this new BiCMOS on a single crystal of silicon nanomembrane with a piece of flexible plastic. This has helped them skip all the hurdles. It took only a week of time for them to do it. In the conventional method, the time is nearly three months. This new method can be also used for commercial purpose.
As per the scientists, the steps are constant all that changed is the mixed signal tools in this case. This is going to expand the horizon of flexible electronics and their commercial implementation.
