Welcome to Advanced Optoelectronic Materials Research Group


Welcome to the Lin Research Group in the Department of Materials Science and Engineering at National Tsing Hua University (NTHU). Led by Prof. Hao-Wu Lin, our team of materials scientists and device engineers is dedicated to pioneering next-generation organic, organic-inorganic hybrid, and nanomaterials.

By bridging the gap between fundamental materials science and cutting-edge device technology, we harness the unique advantages of soft materials—such as large-area scalability and mechanical flexibility—and pair them with exceptional semiconducting performance. Our work spans from foundational discoveries to real-world optoelectronic applications.

Recent research topics include:


  • Perovskite Quantum Dots for Quantum Technologies: Single perovskite quantum dots as quantum light sources (single-photon and entangled-photon emission) for quantum communication and quantum computing, together with the underlying quantum physics of perovskite nanocrystals—exciton fine structure, coherence, photon antibunching, and spin dynamics.
  • Advanced Photovoltaics and Energy Harvesting: All-Vacuum-Deposited Halide Perovskite Solar Cells, Environmental Light Energy Harvesters, and scalable vacuum-deposition techniques for commercialization.
  • Emerging Light-Emitting Technologies (PeLED & QDs): Vacuum-Deposited and Solution-Processed Perovskite LEDs (PeLED) for displays and lighting. Light-Emitting Perovskite Nanocrystals, and Single Perovskite Quantum Dot studies.
  • Brain-Inspired Computing and Memristors: Hardware-Based Neuromorphic Computing Devices, Halide Perovskite Memristors, and Optoelectronic/Photonic Artificial Synapses (including Lead-Free and 2D Perovskites) for artificial intelligence applications.
  • High-Performance Radiation and Photodetectors: All-Vacuum-Deposited Perovskite X-Ray Detectors, Flexible Detectors, and cutting-edge thin-film optoelectronic sensors.
  • Fundamental Photophysics of Emerging Semiconductors: Photon, exciton, and carrier dynamics in halide perovskites and organic thin films, studied by time-resolved and single-emitter spectroscopy to guide the design of higher-performance materials and devices.
