Abstract

The present study proposes a two-step doping strategy for achieving efficient Mg doping of h-BN, involving an additional post-annealing treatment. This approach leads to ∼108-fold enhancement in conductivity of h-BN, compared with the as-doped h-BN grown by low-pressure chemical vapor deposition. The mechanism for large enhancement in h-BN doping efficiency after post-annealing was investigated, providing evidence that this treatment not only facilitates the nanoparticle decomposition and incorporation of Mg atoms into h-BN, but also restores its lattice defects. The efficient two-step doping strategy for p-type h-BN in this study enlightens its promising prospects for ultraviolet optoelectronic devices.

通过高效的两步掺杂策略增强六方氮化硼的 p 型电导率

本研究提出了一种两步掺杂策略，以实现 h-BN 的高效镁掺杂，其中包括额外的退火后处理。与通过低压化学气相沉积法生长的原掺杂 h-BN 相比，这种方法使 h-BN 的电导率提高了～108 倍。研究表明，后退火处理不仅能促进纳米粒子的分解和镁原子在 h-BN 中的掺入，还能恢复 h-BN 的晶格缺陷。本研究中针对 p 型 h-BN 的高效两步掺杂策略启示了其在紫外光电子器件中的广阔前景。
