Block printing to increase the flexibility of electronics

Pollsters at Stanford and the University of California-Los Angeles have popped up with the "block printing", a new process for developing organic semi-conducting crystals onto a surface that can help to produce improved as well as cost effective electronic devices and video screens. The hot procedure is capable of developing individual crystals over a surface already patterned with metal electrodes, therefore, offering an economical and easy technique to create circuitry over a surface.

In block printing technique, single-crystal organic transistors are speedy and have far better charge carrier mobility that results in an immediate transfer of electrical current through the crystal, once they are plugged in. On the other, the existing thin-film transistors, the carbon-based versions of transistor to be usually found in flat panel computer screens just acquire about a third the charge mobility, obviously not too good if compared to the new technique.

Though, the thin-film transistors move quite slow, they are preferred by scientist as they could be produced as a whole, whereas you can make single-crystal devices only through manual selection and placing of individual crystals that is bit complicated than the former.

No doubt, the block printing technique could bring about a certain revolution as well as flexibility in high-performance electronic devices, but lots of work is needed to be done to bring it to the consumer market.
