Silicon-friendly resistive switching memory with tin

In a study published in Nanoscale, researchers show that the variability seen in devices that operate by filament formation and dissolution is linked to differences in device starting local microstructure.

Scientific Achievement

A silicon CMOS-compatible resistive switching memory applicable to 3D crossbar architectures was created.

Significance and Impact

By developing criteria to select electrode metals for cationic filamentary resistive memory devices and demonstrating stable memory device performance under high thermal stress, the potential this structure holds for high density memory cells was confirmed.

Research Details

  • Device characterization included time evolution study of filament formation, revealing microstructural effects on device performance.
  • This work used fabrication, materials characterization, and computational resources at the Center for Nanoscale Materials (CNM) including clean room facilities and transmission electron microscopy (TEM).
