Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

An FIR Filter Using Segmented Photodiodes for Silicon Photodiode Equalization

IEEE Photonics Technology Letters, 2016
This letter presents a finite-impulse response (FIR) filter implemented using segmented photodiodes, which provides a bandwidth enhancement or a partial frequency response equalization for a silicon photodiode. The FIR filter utilizes an $LC$ ladder network for its delay cells, where each segmented photodiode constitutes the ladder network.
