Love-Electronics: Paper Transistor

Paper Transistor:-

Paper transistor is one of the most important inventions in modern times. It revolutionized electronics and unlocked new and much, much smaller circuits. Portuguese researchers have produced the first paper-based transistors. To be more precise, they have made the first field effect transistors (FET) with a paper interstrate layer. According to the research team, these new transistors offer the same level of performance as 'state-of-the-art oxide based thin film transistors (TFTs) produced on glass or crystalline silicon substrates.

A common paper sheet is used on both sides in the fabrication of the paper transistor. It means paper is used instead of silicon which was invented by a Portuguese team and is manufactured at ambient temperature. This way, the paper acts simultaneously as the electric insulator and as the substrate. Furthermore, electric characterization of devices showed that the hybrid FETs' performance outpace those of amorphous silicon TFTs, and rival with the actual state of the art of oxide thin film transistors.

There is an increased interest in the use of biopolymers for low-cost electronic applications. Since cellulose is the Earth's major biopolymer, some international teams have reported using paper as the physical support (substrate) of electronic devices but no one had used paper as an interstrate component of a FET.

The cellulose not only used as substrate but also act as electric insulator by fabricating the device on both sides of the paper. Add to that the paper transistor outperforms the amorphous silicon thin-film transistor used in modern LCD displays and is up to par with the very latest oxide thin-film transistors, which are still a rare sight.

Since paper is a flexible and a biomaterial it would open up new possibilities for bendable displays, bio-labeling, small and cheap displays that could be used for labeling of varies things and more. Our only concern so far is the degradability, i.e. the lifespan of displays made from paper.
These results suggest promising new disposable electronics devices, like paper displays, smart labels, smart packaging, bio-applications and RFID tags.

Transistors on paper become a reality:-

A team over at the Universidade Nova de Lisboa has reportedly figured out a way to use paper (yes, paper) as an interstrate component of a Field Effect Transistor (FET). In testing, the group "fabricated the devices on both sides of the paper sheet," thus causing the paper to act as the "electric insulator and as the substrate" simultaneously. Remarkably, results showed that performance actually rivaled that of best-in-class oxide thin film transistors, giving revived hope for the realm of disposable devices like paper displays, labels, intelligent packaging, tracking tags, etc. The findings are scheduled to be published this September, after which we're sure any firms interested in taking this stuff commercial will be putting their best foot forward.

What's next, paper microprocessors?
A new device which rivals in electrical performance with the actual state of the art of oxide based thin film transistors (TFTs) produced on glass or crystalline silicon substrates.
In a new approach, scientists from Cenimat/I3N – a research group coordinated by Elvira Fortunato and Rodrigo Martins – used a common sheet of paper as the dielectric layer on oxide FETs.
The research team fabricated the devices on both sides of the paper sheet. This way, the paper acts simultaneously as the electric insulator and as the substrate. "Is a two in one," says Elvira Fortunato.

Advantages/disadvantages: -

The pros and cons in comparison with the machines that were used at that time and the special features in comparison with he predecessors. The basic element of the first computer generation was the electron tube. In the second generation the tube was replaced by the transistor. Further computer generations followed. The transistor was invented in 1948 by the Americans John Bardeen, Walter Brattain and William Shockley. In 1955 transistors were produced in series, this paving the way for the second generation of computers.
