Researchers Print Promising Two-Dimensional Transistors

Transistors

Researchers just printed two dimensional transistors successfully

If you are wondering what transistors then please note it is essentially a semiconductor devices which helping amplifying and switching the electronic signals or electric power as a whole. It plays a vital in almost all the electronics products which are available in the market and without it you can’t even think of devices performing the way they are. Some of the researchers from AMBER and Trinity College in Dublin have successfully created printed transistors that consist of only two dimensional nanomaterials. The best thing about this innovation is that no one has done it before and the 2d materials used in comes loaded promising electronic properties which is extremely low cost in nature.
This research does have some of the incredible application potential which can’t be explained to its fullest. For example in future the food packaging industry can make use of it bring a digital countdown which will alert the users about the health of the food and placing it on wine bottle can help in showing whether wine is kept at the optimum temperature or not. Their finding has already been published in the Science magazine April issue.

 

The team behind this technology


Using the standard printing technique of combining the grapheme nanosheets which includes the electrodes with two other nanomaterials namely boron nitride and tungsten diselenide. The two most important parts of the transistors is called the channel and separator and researchers has been able to print it on a nanosheet thereby coming up with a working transistor.

The team of researchers consisted of Trinity College professors namely Jonathan Coleman and Georg Duesberg. Coleman has shed light on the future possibility of creating or combining together highly complex device by conducting, semiconducting as well as insulating the 2D nanomaterials. But during their research they simply focused on printing the transistors which can work as electric switches into the modern computing with ease and grace. 

New method indulge in testing without even touching

Earlier the chemical vapor deposition were used to develop the two dimensional transistors. Using this particular the transistors were great at performance but the method itself was quite expensive.

While the printable electronics brings a new way of printing components which are mostly based on the carbon based molecules at extremely low cost and get an amazing performance out of it at the same time. It is worth noting that carbon based molecules does have its own share instability and performance limitations but it is still better than the chemical vapor deposition.

A single nanosheet can do much better

Researchers has made use of many different nanosheets of completely varying size in order to get best combination available for the printing their transistors. When the printing process was initiated researchers simply deposited the nanosheets over one another in random fashion and it was found that the conductivity present within the nanosheets was just good for the job.

So the next job for the researchers is to come with a single nanosheet which will help in printing such 2D structures which offers better performance than the current one.
