  • Abstract
    The charge-trapping properties of niobium-doped La2O3 have been investigated based on MONOS capacitors. The memory device with niobium-doped La2O3 CTL shows better characteristics than that with pure La2O3 CTL in memory window and P/E properties. It also shows good retention characteristics. Therefore, the niobium-doped La2O3 is a promising candidate as CTL for nonvolatile memory applications.
