A method for growing organic semiconducting crystals onto a surface could lead to better flexible electronic devices and video displays, researchers claim.
Transistors made from thin films of organic semiconductor crystals are crucial to flat panel displays, as well as prototype flexible electronics.
The new "block printing" technique can grow individual crystals on top of a surface previously patterned with metal electrodes. This provides a cheaper and simpler way to create circuitry on a surface, the technique's creators say.
Until now, the only practical way to add electronic components to a surface has involved completely covering it with a semiconducting material onto which these features have previously been added. This is inefficient as the components are often widely dispersed across the surface
