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,

RESTORING OPTICAL LOGIC:DEMONSTRATION OF EXTENSIBLE ALL-OPTICAL DIGITAL SYSTEMS.

, 1987
We show experimentally how nonlinear all-optical circuit elements can be used to create indefinitely extensible optical logic. By using a 'lock and clock' architecture and an off-axis configuration of the power and signal beams, we avoid signal ...
