Abstract

The graphenelike form of carbon nitride is known as 𝑔C3N4, a single sheet of which may be composed of an 𝑠-triazine (𝑆-type) or tri-𝑠-triazine (𝑇-type) periodic lattice with a different size of hole. By employing the first-principles calculation, we find that the difference in the out of plane polarization caused by the symmetry breaking of the 𝑆-type or 𝑇-type structure of bilayer 𝑔C3N4 through interlayer sliding may be related to the size of the in-plane hole. The nonpolar bilayer 𝑔C3N4 (𝑆- or 𝑇-type) state needs to slide about two bond lengths before it is electrically driven to the polar state, resulting in ferroelectric structures with opposite polarization directions. It has been confirmed experimentally and theoretically [Zelisko et al., Nat. Commun. 5, 4284 (2014)] that the anomalous piezoelectric properties of 𝑇-type 𝑔C3N4 monolayer come from their noncentrosymmetric triangular holes. Interestingly, we find here that the 𝑆-type 𝑔C3N4 exhibits the opposite piezoelectric property to the 𝑇-type 𝑔C3N4, that is, a negative longitudinal piezoelectricity (NLP). Our computational analysis shows that the superposition of two reversed triangular holes in the 𝑆-type 𝑔C3N4 plane will result in the emergence of NLP. Hence, the origin of different piezoelectric properties between 𝑆-type and 𝑇-type 𝑔C3N4 is comparatively elucidated. These results provide alternative structural manipulation degrees of freedom for the inherent properties of two-dimensional van der Waals layered semiconductor materials, and expand ferroelectric candidate materials for next-generation nanoelectronic devices.

双层和三层𝑔-C3N4 的面内滑动铁电性和压电性
氮化碳的类石墨烯形式被称为𝑔-C3N4,其单片可能由具有不同孔洞大小的𝑠-三嗪(𝑆型)或三𝑠-三嗪(𝑇型)周期晶格组成。通过第一性原理计算,我们发现双层 𝑔-C3N4 的𝑆型或𝑇型结构通过层间滑动对称性破缺引起的平面外极化差异可能与平面内孔的大小有关。非极性双层 𝑔-C3N4(𝑆- 或 𝑇-型)态需要滑动约两个键长才能电驱动到极性态,从而形成极化方向相反的铁电结构。实验和理论证实 [Zelisko 等人,Nat. Commun. 5, 4284 (2014)],𝑇型 𝑔-C3N4单层的反常压电特性来自于它们的非中心对称三角孔。有趣的是,我们发现𝑆 型 𝑔-C3N4 与 𝑇 型 𝑔-C3N4 具有相反的压电特性,即负纵向压电性 (NLP)。我们的计算分析表明,𝑆 型 𝑔-C3N4 平面上两个反向三角孔的叠加将导致 NLP 的出现。因此,𝑆 型和𝑇 型 𝑔-C3N4 之间不同压电特性的起源得到了比较清晰的阐释。这些结果为二维范德瓦尔斯层状半导体材料的固有特性提供了另一种结构操作自由度,并为下一代纳米电子器件拓展了铁电候选材料。
