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…
Isotropic charge screening of the anisotropic black phosphorus revealed by potassium adatoms
Zhen Tian, Yu Gan, Taiming Zhang +4
Black phosphorus has attracted great research interest due to its numerous applications in electronic devices, optoelectronic devices, energy storages and so on. Compared with the…
The quantum nature of hydrogen
Wei Fang, Ji Chen, Yexin Feng +2
Hydrogen is the most abundant element in the universe. It is also the lightest and as such the most quantum of the elements, in the sense that quantum tunnelling, quantum delocalis…
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…
Lateral heterostructures formed by thermally converting n-type SnSe2 to p-type SnSe
Zhen Tian, Mingxing Zhao, Xiongxiong Xue +5
Different two-dimensional materials, when combined together to form heterostructures, can exhibit exciting properties that do not exist in individual components. Therefore, intensi…
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…
Inverse Temperature Dependence of Nuclear Quantum Effects in DNA Base Pairs
Wei Fang, Ji Chen, Mariana Rossi +3
Despite the inherently quantum mechanical nature of hydrogen bonding, it is unclear how nuclear quantum effects (NQEs) alter the strengths of hydrogen bonds. With this in mind, we…
The quantum nature of the superconducting hydrogen sulfide at finite temperatures
Ying Yuan, Yexin Feng, Lifeng Bian +2
HS is believed to the most possible high-temperature superconducting () phase of hydrogen sulfide at 200 GPa. It's isotope substitution of hydrogen (H) by d…
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…
