Quantifying proximity-induced superconductivity from first-principles calculations
Yunhao Li, Zimeng Zeng, Jizheng Wu +2
Proximity induced superconductivity with a clean interface has attracted much attention in recent years. We discuss how the commonly-employed electron tunneling approximation can b…
Stacking effect and Coulomb correlation in layered charge density wave phase of 1T-NbS2
Wei Wang, Chen Si, Wen Lei +4
Based on first-principles calculations, we explored the interplay between stacking effect and electron-electron correlation in the layered vdW material of bulk 1T-NbS2 with a 2D ch…
Phase Transition in a Memristive Suspended MoS2 Monolayer Probed by Opto- and Electro-Mechanics
Julien Chaste, Imen Hnid, Lama Khalil +8
Semiconducting monolayer of 2D material are able to concatenate multiple interesting properties into a single component. Here, by combining opto-mechanical and electronic measureme…
Defect energetics and magnetic properties of 3d-transition-metal-doped topological crystalline insulator SnTe
Wang Na, Wang Jianfeng, Si Chen +2
The introduction of magnetism in SnTe-class topological crystalline insulators is a challenging subject with great importance in the quantum device applications. Based on the first…
Functionalized Germanene as a Prototype of Large-Gap Two-Dimensional Topological Insulators
Chen Si, Junwei Liu, Yong Xu +3
We propose new two-dimensional (2D) topological insulators (TIs) in functionalized germanenes (GeX, X=H, F, Cl, Br or I) using first-principles calculations. We find GeI is a 2D TI…
Superconducting Graphene: the conspiracy of doping and strain
Chen Si, Zheng Liu, Wenhui Duan +1
Graphene has exhibited a wealth of fascinating properties, but is also known not to be a superconductor. Remarkably, we show that graphene can be made a conventional Bardeen-Cooper…
Electronic Strengthening of Graphene by Charge Doping
Chen Si, Wenhui Duan, Zheng Liu +1
Graphene is known as the strongest 2D material in nature, yet we show that moderate charge doping of either electrons or holes can further enhance its ideal strength by up to ~17%,…
