Inorganic Halide Perovskite Nanowires/Conjugated Polymer Heterojunction-Based Optoelectronic Synaptic Transistors for Dynamic Machine Vision.

Inspired by the retina, artificial optoelectronic synapses have groundbreaking potential for machine vision. The field-effect transistor is a crucial platform for optoelectronic synapses that is highly sensitive to external stimuli and can modulate conductivity. On the basis of the decent optical absorption, perovskite materials have been widely employed for constructing optoelectronic synaptic transistors.

Synthesis of Large-Scale Single-Crystalline Monolayer WS₂ Using a Semi-Sealed Method.

As a two-dimensional semiconductor, WS₂ has attracted great attention due to its rich physical properties and potential applications. However, it is still difficult to synthesize monolayer single-crystalline WS₂ at larger scale. Here, we report the growth of large-scale triangular single-crystalline WS₂ with a semi-sealed installation by chemical vapor deposition (CVD).
