In the present communication, we have investigated the interaction between a biomembrane component 1,2-dioleoyl--glycero-3-phosphocholine (DOPC) and a coagulating protein protamine sulfate (PS) using the Langmuir-Blodgett (LB) technique. The π- isotherm, π- characteristics, and analysis of isotherm curves suggested that PS strongly interacted with DOPC, affecting the fluidity of the DOPC layer. Electrical characterization indicates that PS as well as the PS-DOPC film showed resistive switching behavior suitable for Write Once Read Many (WORM) memory application. Trap-controlled space charge-limited conduction (SCLC) was the key mechanism behind such observed switching. The presence of DOPC affected the SCLC process, leading to lowering of threshold voltage ( ), which is advantageous in terms of lower power consumption.
在本通讯中，我们使用朗缪尔-布洛杰特（LB）技术研究了生物膜成分1,2-二油酰基-sn-甘油-3-磷酸胆碱（DOPC）与凝血蛋白硫酸鱼精蛋白（PS）之间的相互作用。π等温线、π特性以及等温线曲线分析表明，PS与DOPC强烈相互作用，影响了DOPC层的流动性。电学特性表明，PS以及PS-DOPC膜表现出适合一次写入多次读取（WORM）存储器应用的电阻切换行为。陷阱控制的空间电荷限制传导（SCLC）是这种观察到的切换背后的关键机制。DOPC的存在影响了SCLC过程，导致阈值电压（ ）降低，这在较低功耗方面是有利的。
