Resonant Band Engineering of Ferroelectric Tunnel Junctions
Jing Su, Xingwen Zheng, Zheng Wen +5
We propose energy band engineering to enhance tunneling electroresistance (TER) in ferroelectric tunnel junctions (FTJs). We predict that an ultrathin dielectric layer with a small…
Spin soliton of Holstein model with spin-orbit coupling in one-dimensional conjugated polymers
Shijie Xie, Xiaohui Liu, Qiuxia Lu +1
For Holstein model with Rashba spin-orbit coupling (SOC) we establish the nonlinear Schrödinger equations and obtain exact soliton solution analytically. It is found that the solit…
Controlling valley splitting and Polarization of dark- and bi-excitons in monolayer WS by a tilted magnetic field
Fanyao Qu, Helena Bragança, Railson Vasconcelos +3
We developed a comprehensive theoretical framework focusing on many-body effects of exciton species in monolayer WS, including bright and dark excitons, and intra- and inter-va…
Realization of Lieb Lattice in Covalent-organic Frameworks with Tunable Topology and Magnetism
Bin Cui, Xingwen Zheng, Jianfeng Wang +3
Lieb lattice, a two-dimensional edge-depleted square lattice, has been predicted to host various exotic electronic properties due to its unusual band structure, i.e., Dirac cone in…
Bias-induced insulator-metal transition in organic electronics
J. H. Wei, Yijing Yan, S. J. Xie +1
We investigate the bias-induced insulator-metal transition in organic electronics devices, on the basis of the Su-Schrieffer-Heeger model combined with the non-equilibrium Green's…
