本論文即探討因La2-xSrxNiO4(LSNO)靜態的電荷及電子自旋(static charge stripes and spin stripes)的條狀結構形成，使其在低溫下仍不具有超導性，因其異質同構物(isostructure) La2-xSrxCuO4在Sr摻雜至15%時會在35K卻出現超導特性，故本文從電壓-電流(V-I)及電流-電壓(I-V)的電性量測去觀察知，在量測上的結果會呈現一非線性關係的傳輸行為，並從不同的軸向去探討其電荷條紋對LSNO的影響。 In this dissertation I present the experimental results of the non-linear transport property of the La5/3Sr1/3NiO4 which undergoes a metal-insulator transition at T 230K because of the formation of charge stripes. La5/3Sr1/3NiO4 is an isostructural material of the high-TC superconductor La2-xSrxCuO4, and therefore it serves a contrast system for the study of high-TC superconductor. In order to understand the nonlinear behavior caused by CDW, I measured the I-V and V-I curve at different temperatures along the three crystallographic axes H, K, and L, respectively.
