Two-dimensional perovskites as sensitive strain sensors

Two-dimensional (2D) organic-inorganic lead halide perovskites have attracted intensive attention for optoelectronic applications. Principally, strain-induced octahedral distortion in these materials may open up new application scope through modulation of carrier transport. However, they have never...

Zusammenfassung:Two-dimensional (2D) organic-inorganic lead halide perovskites have attracted intensive attention for optoelectronic applications. Principally, strain-induced octahedral distortion in these materials may open up new application scope through modulation of carrier transport. However, they have never been explored as strain sensors. Moreover, traditional strain sensors are troubled by their limited sensitivity at a low strain ratio (
