Journal ArticleDOI
Synergistic Gating of Electro-Iono-Photoactive 2D Chalcogenide Neuristors: Coexistence of Hebbian and Homeostatic Synaptic Metaplasticity.
Rohit Abraham John,Fucai Liu,Nguyen Anh Chien,Mohit Rameshchandra Kulkarni,Chao Zhu,Qundong Fu,Arindam Basu,Zheng Liu,Nripan Mathews +8 more
TL;DR: Exploiting a novel multigated architecture incorporating electrical and optical biases, this incarnation not only addresses different charge‐trapping probabilities to finely modulate the synaptic weights, but also amalgamates neuromodulation schemes to achieve “plasticity of plasticity–metaplasticITY” via dynamic control of Hebbian spike‐time dependent plasticity and homeostatic regulation.
Journal ArticleDOI
Flexible Ionic‐Electronic Hybrid Oxide Synaptic TFTs with Programmable Dynamic Plasticity for Brain‐Inspired Neuromorphic Computing
Rohit Abraham John,Jieun Ko,Mohit Rameshchandra Kulkarni,Naveen Tiwari,Nguyen Anh Chien,Ng Geok Ing,Wei Lin Leong,Nripan Mathews +7 more
TL;DR: Artificial synapses based on ionic-electronic hybrid oxide-based transistors on rigid and flexible substrates are demonstrated demonstrating concurrent processing and memory functionalities with spatiotemporal correlation.
Journal ArticleDOI
Ionotronic Halide Perovskite Drift-Diffusive Synapses for Low-Power Neuromorphic Computation.
Rohit Abraham John,Natalia Yantara,Yan Fong Ng,Govind Narasimman,Edoardo Mosconi,Daniele Meggiolaro,Mohit Rameshchandra Kulkarni,Pradeep Kumar Gopalakrishnan,Chien A. Nguyen,Filippo De Angelis,Subodh Mhaisalkar,Arindam Basu,Nripan Mathews +12 more
TL;DR: Network-level simulations of unsupervised learning of handwritten digit images utilizing experimentally derived device parameters, validates the utility of these memristors for energy-efficient neuromorphic computation, paving way for novel ionotronic neuromorphic architectures with halide perovskites as the active material.
Journal ArticleDOI
Facile Water-based Spray Pyrolysis of Earth-Abundant Cu2FeSnS4 Thin Films as an Efficient Counter Electrode in Dye-Sensitized Solar Cells
Rajiv Ramanujam Prabhakar,Nguyen Huu Loc,Mulmudi Hemant Kumar,Pablo P. Boix,Sun Juan,Rohit Abraham John,Sudip Kumar Batabyal,Lydia Helena Wong +7 more
TL;DR: This is the first report on the electrical properties of solution-processed Cu2FeSnS4 thin films estimated using Hall measurements, indicating that CFTS would be a promising cheaper alternative to replace Pt as a counter electrode in DSSCs.
Journal ArticleDOI
