Monolayer cubic boron (B) nitride (N) terminated diamond (111) surfaces are proposed and investigated using density functional theory. The carbon (C)–N–B-terminated diamond (111) surface with a monolayer coverage of hydrogen and the C–N–B-terminated diamond (111) surface with a monolayer coverage of fluorine [named C–N–B–F-terminated (111) surface] have positive electron affinities (PEAs) with no inter-band gap states and nearly perfect alignment of nitrogen vacancy (NV). Thus, they could potentially be applied in NV-based quantum sensors. The C–B–N-terminated diamond (111) surface with a monolayer coverage of hydrogen [named C–B–N–H-terminated (111) surface], which has negative EAs (NEAs) and an adsorption energy of −3.51 eV, could potentially be employed in electron emission devices. Specifically, C–N–B–F- and C–B–N–H-terminated diamond (111) surfaces have the largest PEA (4.48 eV) and NEA (−4.00 eV), respectively, of any reported diamond surfaces. We also propose a formalism to construct multiple dipole structures on diamond surfaces to yield extremely large EAs.

单层立方氮化硼终止的金刚石(111)表面,用于量子传感和电子发射应用。
提出并利用密度泛函理论研究了单层立方氮化硼(B)终止于金刚石(111)的表面。单层覆盖氢的碳(C)–N–B端金刚石(111)表面和单层覆盖氟的C–N–B端金刚石(111)表面[命名为C–N–B–具有F末端(111)的表面]具有正电子亲和力(PEA),没有带间隙态,并且氮空位(NV)几乎完美对准。因此,它们有可能被应用在基于NV的量子传感器中。C–B–N端接的金刚石(111)表面单层覆盖氢(称为C–B–N–H端接的(111)表面),其EA值为负(NEA),吸附能为-3.51 eV,有可能在电子发射设备中使用。特别,C–N–B–F–和C–B–N–H端接的钻石(111)表面在所有报告的钻石表面中分别具有最大的PEA(4.48 eV)和NEA(−4.00 eV)。我们还提出了一种形式主义,即在钻石表面上构造多个偶极结构,以产生非常大的EA。
