Breaking the Sabatier Principle by Dynamic Adsorption-Desorption Decoupling in Electrocatalytic Hydrogen Evolution
Zi-Xuan Yang, Lei Li, Tao Huang +5
The Sabatier principle establishes a fundamental trade-off in heterogeneous electrocatalysis.In the hydrogen evolution reaction (HER), this trade-off is manifested by the coupling…
Electronic origin of stability of 2D 1H-phase Janus transition metal dichalcogenides and beyond
Lei Li, Ji-Chun Lian, Zi-Xuan Yang +8
Janus transition metal dichalcogenides (JTMDs) monolayers have emerged as a new paradigm to broaden the family of two-dimensional (2D) materials. Despite numerous theoretical predi…
Doping-free Janus homojunction solar cell with efficiency exceeding 23%
Lei Li, Zi-Xuan Yang, Tao Huang +6
Photovoltaic solar cell is one of the main renewable energy sources, and its power conversion efficiency (PCE) is improved by employing doping or heterojunction to reduce the photo…
Symmetry-breaking-induced giant Stark effect in 2D Janus materials
Jiang-Yu Lu, Wu-Yu Chen, Lei Li +6
Symmetry breaking generally induce exotic physical properties, particularly for low-dimensional materials. Herein we demonstrate that symmetry breaking induces a giant Stark effect…
Symmetry-breaking-induced multifunctionalities of two-dimensional chromium-based materials for nanoelectronics and clean energy conversion
Lei Li, Tao Huang, Kun Liang +5
Structural symmetry-breaking that could lead to exotic physical properties plays a crucial role in determining the functions of a system, especially for two-dimensional (2D) materi…
