Summary

• What is new: This research explores monolayers of ordered boron-based group-III nitride alloys, specifically studying their electronic properties and stability, introducing the novel concept of out-of-plane atomic puckering that leads to polar ordering and antiferroelectric states.
• Why this is important: Existing UWBG semiconductors like GaN and SiC are limited by their operational parameters. This research seeks alternatives that can function efficiently at even higher voltages, frequencies, and temperatures.
• What the research proposes: The study proposes using monolayers of a new material—boron-based group-III nitride alloys—with a unique structural feature of out-of-plane puckering of atoms, which significantly contributes to stability and electronic efficiency.
• Results: The ab initio calculations provided in the study confirm the energetic and dynamic stability of these monolayers, thereby identifying them as promising candidates for high-efficiency power electronics.
