本研究在 MIM 元件的電流傳導機制研究，概括出一個粗略的輪廓，然而對 於 Ni/TiO2_60nm/Ni 的元件來說，其三階段的電流傳導現象依然有一些盲點需要 解釋。我們在第一階段小電壓時以 P-F conduction 主導以及大電壓時 field emission 主導的電流機制，以公式進行電流擬和可以符合趨勢，但第二階段的電 流上升區域，尚未找到公式進行電流擬和。未來希望利用變溫以及 pulse IV 的量 測數據，來反推出 Ni/TiO2的蕭基能障大小，以及擬和出完整的電流曲線。
另外在脈衝式電壓電流量測部分，目前量測的最高頻率限制於 500kHz，再 將頻率向上提升便會出現無法解釋的電流現象，估計是由於電路中非理想寄生電 容電感造成的誤差，因此無論是在量測儀器的安排上，或是量測程式的設定上，
都還有一定進步的空間。
