研究目的
To improve the resistive switching characteristics of ReRAMs by proposing a HfOx/SiC bilayer structure and demonstrating its improved characteristics compared to single-layer devices.
研究成果
The HfOx/SiC bilayer structure significantly improves the memory characteristics of ReRAM devices, including larger memory windows, lower operating voltages, and excellent endurance and retention characteristics. The high transmittance of the bilayer also makes it suitable for transparent electronic devices.
研究不足
The study focuses on the improvement of resistive switching characteristics by stacking SiC and HfOx layers but does not explore the scalability of the devices or their integration into existing semiconductor manufacturing processes.
