Silicon-based inorganic-organic hybrid optoelectronic synaptic devices simulating cross-modal learning

With advances in Si-based technology infrastructures and the rapid integration of Si-based optoelectronics, Si-based optoelectronic synaptic devices have the potential to greatly facilitate the large-scale deployment of neuromorphic computing. The incorporation of solution-processable polymer semiconductors into Si-based optoelectronics may enable the cost-effective fabrication of optoelectronic synaptic devices. Poly(3-hexylthiophene) (P3HT) is a semiconducting polymer used to manufacture optoelectronic synaptic transistors with P3HT channels and Si gates. The gate dielectric between them consists of a SiO2 layer. Hybrid inorganic-organic Si/P3HT optoelectronic synaptic transistors can mimic synapses when exposed to optical and electrical stimuli. The Si/P3HT synaptic devices can spatiotemporally integrate optical and electrical stimuli to mimic cross-modal learning.
