High‐κ Perovskite‐Like Ternary Niobium Oxide Dielectrics for 2D Electronics

Advanced Materials, EarlyView.
High‐κ dielectrics are vital for scaled electronics. Here, a family of 2D high‐κ perovskite‐like ternary niobium oxides is synthesized via a molten salt‐assisted method. Their integration into FETs and logic gates reveals superior switching characteristics, providing a fresh material platform and new insights for the advancement of high‐performance 2D ...

Ambient pressure synthesis of ternary group(V) nitrides

Journal of Solid State Chemistry, 1992
Abstract We describe the ambient pressure synthesis of MTaN2 (M = Na or K), and the previously unreported, isostructural niobium analogs by the use of an ammonia flow system, starting with either Ta3N5 or tantalum metal, or either NbN or niobium metal, respectively, and an excess of the alkali metal amide at 500°C. The products are characterized by X-
