Figure 6From: Gadolinium oxide nanocrystal nonvolatile memory with HfO2/Al2O3 nanostructure tunneling layersRetention characteristic and extracted activation energy. (a) The retention characteristic at 25°C of Gd2O3-NC memories with nanostructure tunneling layer. (b) The extracted activation energy of two charge loss mechanisms. The retention characteristic can be divided into two parts which have different charge loss rates.Back to article page
