Phototransistors: Flexible Phototransistors Based on Single‐Crystalline Silicon Nanomembranes (Advanced Optical Materials 1/2016)

Flexible phototransistors with a back-gate configuration based on transferrable single-crystalline Si nanomembranes (Si NM) are demonstrated by Z. Ma and co-workers on page 120. Having the Si NM as the top layer enables full exposure of the active region to any incident light and thus allows effective light sensing. Highly sensitive light detection and stable performance under bending conditions offer great promise for high-performance, flexible, optical sensor applications, with easy integration for multifunctional applications.
