Metal oxide optoelectronic synapses are promising for neuromorphic vision, but combining a low dark current with sustained photoinduced plasticity remains challenging.
Description
Here, Al stoichiometry is engineered in electrospun In<sub>1</sub>Al<sub><i>x</i></sub>Zn<sub>0.08</sub>O (<i>x</i> = 0.007, 0.011, and 0.015) nanofiber networks to tune sub-bandgap defects, carrier transport, and photocarrier relaxation. Optical, spectroscopic, electrical, and synaptic measurements identify 1.1 atomic % Al as optimal.
Strong Al–O bonding suppresses excess oxygen-vacancy-related donor states while preserving the In 5s transport network. The optimized device shows an off-state current of 10<sup>–11</sup> A, an on/off ratio of 10<sup>7</sup>, a field-effect mobility of 14 cm<sup>2</sup> V<sup>–1</sup> s<sup>–1</sup>, and a paired-pulse facilitation index of 271%. Under pulsed UV light, defect-assisted trapping and slow relaxation retain 30% of the peak photocurrent after 2 h.
