Persistent Interfacial Topological Hall Effect Demonstrating Electrical Readout of Topological Spin Structures in Insulators
Jing Li, Huilin Lai, Andrew H. Comstock +12
Conventional topological Hall effects (THE) require conducting magnets, leaving insulating systems largely inaccessible. Here we introduce the interfacial topological Hall effect (…
Rewritable Complementary Nanoelectronics Enabled by Electron-Beam Programmable Ambipolar Doping
Qing Lan, Wenqing Song, Siyin Zhu +13
The ability to reversibly and site-selectively tune ambipolar doping in a single semiconductor is crucial for reconfigurable electronics beyond silicon, but remains highly challeng…
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,…
A self-learning magnetic Hopfield neural network with intrinsic gradient descent adaption
Chang Niu, Huanyu Zhang, Chuanlong Xu +14
Physical neural networks using physical materials and devices to mimic synapses and neurons offer an energy-efficient way to implement artificial neural networks. Yet, training phy…
