This study introduces a 3D perovskite nanowire array architecture that overcomes uniformity and stability issues in memristors for neuromorphic computing. This innovation enables robust, high-performance perovskite-based neuromorphic hardware.

Area of Science:

  • Materials Science
  • Neuroscience
  • Computer Engineering

Background:

  • Passive memristor crossbars offer high-density, low-power neuromorphic computing.
  • Perovskite memristors are reconfigurable but suffer from uniformity, variability, and instability issues, hindering large-scale integration.

Purpose of the Study:

  • To overcome limitations of perovskite memristors for neuromorphic computing.
  • To demonstrate a 3D perovskite nanowire array architecture with controlled analog conductance modulation.
  • To integrate these memristors into a functional neuromorphic system for biological data analysis.

Main Methods:

  • Engineered a 3D perovskite nanowire array architecture with an ITO barrier.
  • Characterized memristor performance including conductance states, retention, endurance, and variability.

  • Integrated memristors into a 64x64 crossbar array and developed a multi-layer perceptron.

    • Main Results:

    • Achieved 139 non-overlapping Ohmic conduction states (10-100 µS).
    • Demonstrated long retention (>10^6 s) and high endurance (>4x10^5 cycles).
    • Exhibited minimal device-to-device (<5%) and cycle-to-cycle (<1.5%) variability.

    Conclusions:

    • The 3D perovskite nanowire array architecture with ITO barrier overcomes perovskite memristor limitations.
    • The developed memristors enable robust, scalable perovskite-based neuromorphic hardware.
    • Successfully applied the neuromorphic system to analyze zebrafish head and jaw movements.
