摘要：

Pt/LiCoO2/SiO2/Si stacks are fabricated by pulsed laser deposition and annealed at different annealing temperature. Pt/LiCoO2/SiO2/Si stacks exhibit lower current and higher high resistance state/low resistance state ratio than other stacks with homogeneous resistive switching. It is found that resistive switching behavior of Pt/LiCoO2/SiO2/Si stacks can be modulated by LiCoO2 crystal structures. The Pt/LiCoO2/SiO2/Si stacks with R-3m LiCoO2 phase show larger maximum currents and better state stability than samples with amorphous LiCoO2, and samples with amorphous or R-3m LiCoO2 phase exhibit non-homogeneous or homogeneous resistive switching, respectively. The reasons for the different resistive switching behaviors are investigated and discussed. These findings provide insights into how to improve the performance of Pt/LiCoO2/SiO2/Si stacks and a further understanding of the homogeneous resistive switching behavior.
