#277 More on flexibility

Mechanical flexibility of semiconductor electronic and photonic systems is currently a very big deal in semiconductor science and engineering. Flexible displays, flexible sensors, flexible solar cell panels, flexible LED-based lighting panels, flexible bioelectronic devices and integrated circuits are in the process of moving sizable segments of semiconductor industry into the entirely new territory. As you tell from my past blogs (e.g. #258 and 259) I found opening of this new avenue for applications of semiconductors truly exciting.

The interest in flexibility of semiconductor devices was sparked by the progress in making organic semiconductors a commercial reality. As a reminder, organic semiconductors maintain their physical properties even when extremely flexed, thus, making flexible electronics and photonics feasible. Problem is that organic compounds are really not the best semiconductors in terms of physical properties. Wouldn't it be nice if for instance normally rigid and brittle crystalline silicon could be made into a flexible substrate? Well, it turns out that it is entirely feasible. I recommend you take a look at this paper to learn more about flexible silicon. Very interesting...
