Figure 4From: Gadolinium oxide nanocrystal nonvolatile memory with HfO2/Al2O3 nanostructure tunneling layersThe C-V curves. The C-V curves of the fresh, programming (at 10 V, 1 ms) and erasing (at 11 V, 1 s) states for all samples. All the gate voltages were normalized with the VFB of the fresh-state C-V curve (VFBf).Back to article page
