Giant-exchange-driven Vectorial Control of a Minimal Topological Magnet in Eu3In2As4
Haonan Chen, Xunkai Duan, Guangyi Wang +13
The interplay between magnetism and band topology provides a route to controlling quantum states of matter, yet its realization in materials is often constrained by weak exchange c…
Defect Engineering for Stabilizing Magnetic and Topological Properties in Mn(Bi1-xSbx)2Te4
Haonan Chen, Jiayu Wang, Huayao Li +18
MnBi2Te4 is a versatile platform for exploring diverse topological quantum states, yet its potential is hampered by intrinsic antisite defects. While Sb substitution has been emplo…
Quantized Topological States and Parity Anomaly in Intrinsic Quantum Anomalous Hall Insulator MnBi2Te4
Zhongxun Guo, Jingjing Gao, Zhiwei Huang +22
When thinned down to just a few atomic layers, the layered magnetic topological insulator MnBi2Te4 offers an exceptional platform for exploring a wide range of topological phenomen…
Coherent detection of the oscillating acoustoelectric effect in graphene
Yicheng Mou, Jiayu Wang, Haonan Chen +9
In recent years, surface acoustic waves (SAWs) have emerged as a novel technique for generating quasiparticle transport and band modulation in condensed matter systems. SAWs intera…
Unexpected large electrostatic gating by pyroelectric charge accumulation
Yicheng Mou, Qi Liu, Jiaqi Liu +10
Pyroelectricity refers to the accumulation of charges due to changes in the spontaneous polarization of ferroelectric materials when subjected to temperature variations. Typically,…
Broadband photoresponse enhancement by band engineering in Sb-doped MnBi2Te4
Zixuan Xu, Haonan Chen, Jiayu Wang +11
Topological materials have attracted considerable attention for their potential in broadband and fast photoresponse, particularly in the infrared regime. However, the high carrier…
