Isotropic or anisotropic screening in black phosphorous: can doping tip the balance?
Zhimin Liu, Ye Yang, Yueshao Zheng +2
Black phosphorus (BP), a layered van der Waals (vdW) crystal, has unique in-plane band anisotropy and many resulting anisotropy properties such as the effective mass, electron mobi…
A ferroelectric problem beyond the conventional scaling law
Qi-Jun Ye, Zhi-Yuan Liu, Yexin Feng +2
Ferroelectric (FE) size effects against the scaling law were reported recently in ultrathin group-IV monochalcogenides, and extrinsic effects (e.g. defects and lattice strains) wer…
Hydrogenation Facilitates Proton Transfer Through Two-Dimensional Honeycomb Crystals
Yexin Feng, Ji Chen, Wei Fang +3
Recent experiments have triggered a debate about the ability of protons to transfer through individual layers of graphene and hexagonal boron nitride (h-BN). However, calculations…
Direct observation of ordered configurations of hydrogen adatoms on graphene
Chenfang Lin, Yexin Feng, Yingdong Xiao +7
Ordered configurations of hydrogen adatoms on graphene have long been proposed, calculated and searched for. Here we report direct observation of several ordered configurations of…
