The nitrogen-doped (N-doped) LaB₆ has low resistivity, low work function, and chemical stability. We have reported the thin film quality of N-doped LaB₆ electrode (metal : M) and formation of LaB_xN_y (insulator: I) thin film by Ar/N₂ plasma sputtering. In this study, the MIMIS structure diode was investigated to floating-gate memory.
