Research

My research interests lie in neuromorphic computing, probabilistic computing, and quantum computing. The primary focus of my PhD work involves exploring materials science to develop hardware for neuromorphic computing applications. Specifically, I have conducted research on oxygen transport in memristive devices and the development of high-temperature electrochemical random-access memory.

	Thermodynamic Origin of Nonvolatility in Resistive Memory Jingxian Li, Anirudh Appachar, Sabrina L. Peczonczyk, Elisa T. Harrison, Brianna Roest, Anton V. Ievlev, Ryan Hood, Sangmin Yoo, Kai Sun, A. Alec Talin, Wei D. Lu, Suhas Kumar, Wenhao Sun, Yiyang Li* Under Review, 2022 We reveal that the formation and stability of conductive filaments crucially depend on the stability of the amorphous oxygen-rich and oxygen-poor compounds, which undergo composition phase separation.
	Electrochemical and thermodynamic processes of metal nanoclusters enabled biorealistic synapses and leaky-integrate-and-fire neurons Jingxian Li, Yuchao Yang, Minghui Yin, Xinhao Sun, Lidong Li, and Ru Huang* Mater. Horiz., 2020, 7, 71-81 Our study employs the electrochemical migration and thermodynamic relaxation of silver nanoclusters within dielectric materials to accurately mimic the dynamic processes of synapses and neurons in biological systems.
	Tuning analog resistive switching and plasticity in bilayer transition metal oxide based memristive synapses Jingxian Li, Qingxi Duan, Teng Zhang, Minghui Yin, Xinhao Sun, Yimao Cai, Lidong Li, Yuchao Yang, and Ru Huang* RSC Adv., 2017, 7, 43132-43140 We report a systematic study on the analog switching of bilayer oxide based memristive synapses and show that transition metal oxides with rich intermediate phases, are able to provide larger number of conductance states compared with oxides with few intermediate phases.
	Design, synthesis and characterization of a new blue phosphorescent Ir complex Chuang Yao†, Jingxian Li†, Jinshan Wang, Xinjun Xu, Ronghua Liu, and Lidong Li J. Mater. Chem. C, 2015, 3, 8675-8683 We synthesized a novel phosphorescent dye, Cz-C8-FIrpic, which effectively inhibits the phase aggregation of FIrpic units. Devices incorporating Cz-C8-FIrpic exhibited approximately a 15% enhancement in performance compared to the control devices reliant on FIrpic.

Side Projects

Automatic Phase Characterization of Additively Manufactured Materials

We develop two learning based computer vision systems, based of the Unet++ and Segment Anything models, to automatically identify and label the phase fractions of common constituents inside steels using semantic segmentation approaches.

From 3D Gaussian Splatting to 3D Generative Model

We explore the challenge of generating 3D models from single or sparse-view 2D images that use advanced neural architectures and techniques like 3D Gaussian splatting for detailed model generation. We provide a series of evaluations that demonstrate significant advances in generative models that bridge the gap between 2D inputs and 3D outputs.
