Why strained semiconductors are like crinkle cut crisps [poster] Open Access
When applying strain to semiconductors, it has been observed that the bangap (the energy difference between the furthest energy level attached to the atom and the free electrons) changes accordingly. This opens up great possibilities in terms of new sensors which triangulate the change in charge transport, due to the change in bandgap, to calculate where the touch has occurred. This can be extended to design new touch screens and synthetic skin. Unfortunately, while the semiconductors themselves can withstand the strain, the electrodes, added to allow current to flow, cannot. They experience either delamination from the flexible substrate, or cracking, resulting in them becoming nonconductive. My current research is focusing on fixing these issues, making the electrodes more robust, so that I can then investigate the effects of strain on other semiconductor qualities in order to better understand the electrostatics and charge transport of the material. Crinkle cut crisps taste better because they hold more salt, crinkle cut semiconductors insulate better because they hold more electrons.
