Abstract

The gap state density of nano-crystalline silicon active layers on a flexible substrate was redistributed with mechanical bending. The weak or broken bonds may contribute to the redistribution of trap states. During mechanical strain, the deep states redistributed in a Gaussian distribution, and are dissimilar to ordinary acceptor-like deep states, which manifest with exponential distributions. We conclude that the gap state density with TCAD modeling under mechanical strain is the fundamental reliability issue for the development of flexible electronics.
