Electrochemically Exfoliated Amorphous TaIrTe 4 Nanosheets for Bidirectional Optical Neuromorphic Devices

Puntos clave

• This research aims to explore the use of electrochemically exfoliated amorphous nanosheets in neuromorphic devices for efficient signal processing.
• Devices were constructed using amorphous TaIrTe4 nanosheets to study electrical and optical properties.
• Wavelength-selective excitation was conducted between 405 nm and 638 nm to assess conductance changes.
• Neuromorphic network simulations were performed based on experimental data to evaluate performance on the MNIST dataset.
• Photocurrents were generated upon optical stimulation, demonstrating persistent self-powered behavior.
• Conductance potentiation and depression were reversible, revealing effective synaptic plasticity.
• Achieved 92.1% accuracy on the MNIST dataset with ultralow energy consumption (< 5.65 pJ per pulse).
