Adsorption of organic molecules can be a better choice than traditional chemical doping to achieve effective doping of 2D materials. The adsorption of organic molecules on square/octagon‐phase (S/O‐phase) arsenene is investigated and promoted the possibility of developing p–n junctions. In particular, it is found that adsorption of F4‐TCNQ or TCNE molecules leads to effective p‐doping. Adsorption of DMPD or TTF molecules leads to less effective n‐doping. Interestingly, in the case of TTF adsorption strain engineering can be used to greatly improve the material properties. Therefore, both effective n‐ and p‐doping of S/O‐phase arsenene can be realized.

通过吸附有机分子有效掺杂方/八方相砷

与传统的化学掺杂相比，有机分子的吸附是实现2D材料有效掺杂的更好选择。对方形/八边形（S / O相）砷上有机分子的吸附进行了研究，并促进了建立PN连接的可能性。特别是，发现F4-TCNQ或TCNE分子的吸附可导致有效的p掺杂。DMPD或TTF分子的吸附会导致n掺杂效率降低。有趣的是，在TTF的情况下，可以使用吸附应变工程技术极大地改善材料性能。因此，可以实现S / O相砷的有效n掺杂和p掺杂。
