Progress and Prospect of AI in ARPES Workflow
Sandy Adhitia Ekahana, Aalok Tiwari, Pratik Saud +4
Artificial intelligence (AI) is becoming an increasingly useful tool across the experimental sciences, including angle-resolved photoemission spectroscopy (ARPES), which routinely…
Element-Specific Visualization of Layer-Parity and Twist-Dependent Magnetism in CrSBr
Aalok Tiwari, Shubhada Patil, Ravi Kumar Bandapelli +16
Van der Waals (vdW) based antiferromagnets (AFMs) are an ideal platform for probing and understanding thickness- and twist-angle-dependent emergent spin phenomena. However, element…
Imaging of van der Waals Materials via Standing-Wave Photoemission Microscopy: Depth-Resolved Electronic Structure of WS2
J. R. Paudel, R. Muzzio, M. E. Matzelle +13
Two-dimensional van der Waals materials promise electronic, optoelectronic, and quantum technologies, yet depth-resolved characterization remains challenging. Here, we demonstrate…
Electrically tunable interfacial thermal conduction via electronic structure engineering in / topological insulators
Min Young Kim, Joon Sang Kang, Jangwoo Ha +8
This work provides direct experimental evidence for the role of topological interface states in thermal conduction across a metal/topological insulator junction. It also shows that…
Enabling Electrical Readout of Néel vector reversal in a van der Waals Antiferromagnet
Raghvendra Posti, Ravi Kumar Bandepalli, Wenhao Liu +14
Owing to its robustness against external perturbations and intrinsically ultrafast dynamics, the Néel vector in antiferromagnets (AFMs) can enable the development of next-generatio…
Ultrafast Light-Induced Magnetoelectric Effect in van der Waals Magnetic Semiconductor Heterostructures
Wenyi Zhou, Ravi Kumar Bandapelli, Hari Paudyal +8
Atomic-scale heterostructures of van der Waals (vdW) magnets and semiconductors provide a unique environment for exploring magnetic dynamics. In contrast to typical photothermal ex…
