Project C7 will approach the ultimate scaling limits by analyzing the factors determining the filament for-mation and stabilization at the atomic scale. These scalability limits arise from the size of a reliably switching filament and its maximal density and will be analyzed on defect engineered epitaxial thin films (from C2) and crystalline nanoparticles (from C1). SPM methods will be employed to study the change of the surface morphology and the electronic properties during the switching process. Besides crystal stoi-chiometry of the crystal phases, surface adsorbates will be evaluated regarding their potential facilitation of filament formation and dissolution.

C7项目将通过分析在原子尺度上决定细丝形成和稳定的因素来接近最终的标度极限。这些可扩展性限制来自可靠切换灯丝的大小及其最大密度，并将在缺陷工程外延薄膜（来自C2）和晶体纳米颗粒（来自C1）上进行分析。SPM方法将被用来研究开关过程中的表面形貌和电子性质的变化。除了晶相的晶体化学计量学，还将评估表面吸附物对细丝形成和溶解的潜在促进作用。
