Interface engineering creates uniform 2D material arrays for neuromorphic hardware. This overcomes device variability, enabling scalable, energy-efficient optoelectronic reservoir computing and edge intelligence applications.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Neuromorphic Engineering

Background:

  • Two-dimensional (2D) materials are promising for energy-efficient optoelectronic reservoir computing (RC) and neuromorphic hardware.
  • Device-to-device variability, caused by material defects, hinders the scalability of 2D material-based systems.

Purpose of the Study:

  • To develop a scalable and uniform reservoir array using 2D materials for neuromorphic hardware.
  • To address the challenge of device variability in 2D material-based systems.

Main Methods:

  • Engineered vertical p-GaN/n-MoS2 heterojunctions.
  • Utilized a controlled thermal pretreatment to create a uniform GaOx interlayer with homogeneous defects.
  • Leveraged defects as reproducible carrier trapping centers for memory effects.
