Mixed-Dimensional Floating Gate Phototransistors for Mixed-Modal In-Sensor Reservoir Computing.

ABSTRACT: Novel neuromorphic devices constructed from low-dimensional materials have demonstrated significant potential in visual perception and information processing. Colloidal quantum dots (QDs) exhibit strong light absorption and tunable band gaps, while 2D materials provide smooth interfaces and channels with superior charge carrier mobility. However, the potential of devices utilizing QDs as floating gates and 2D materials as channels remains largely underexplored. Herein, a floating-gate phototransistor based on the mixed-dimensional heterostructure of 0D-CsPbBr₃ QDs and 2D-MoS₂ few layer is introduced. By leveraging the optical advantages of 0D-QDs and the electrical properties of 2D materials, mixed-modal in-sensor reservoir computing (RC) is realized. Upon electrical/
