Layer-by-layer disentanglement of Bloch states via frequency-domain photoemission
Woojoo Lee, Sebastian Fernandez-Mulligan, Hengxin Tan +8
Layer-by-layer material engineering has enabled exotic quantum phenomena such as interfacial superconductivity and the quantum anomalous Hall effect. Meanwhile, deciphering electro…
An Integrated Quantum Material Testbed with Multi-Resolution Photoemission Spectroscopy
Chenhui Yan, Emanuel Green, Riku Fukumori +7
We present the development of a multi-resolution photoemission spectroscopy (MRPES) setup which probes quantum materials in energy, momentum, space, and time. This versatile setup…
Delicate Ferromagnetism in MnBiTe
Chenhui Yan, Yanglin Zhu, Leixin Miao +9
Tailoring magnetic orders in topological insulators is critical to the realization of topological quantum phenomena. An outstanding challenge is to find a material where atomic def…
Origins of electronic bands in antiferromagnetic topological insulator MnBiTe
Chenhui Yan, Sebastian Fernandez-Mulligan, Ruobing Mei +7
Despite the rapid progress in understanding the first intrinsic magnetic topological insulator MnBiTe, its electronic structure remains a topic under debates. Here we perfo…
Evidence for d-wave superconductivity in single layer FeSe/SrTiO3 probed by quasiparticle scattering off step edges
Zhuozhi Ge, Chenhui Yan, Huimin Zhang +3
The de Gennes extrapolation length is a direction dependent measure of the spatial evolution of the pairing gap near the boundary of a superconductor, and thus provides a viable me…
Electrical detection of current generated spin in topological insulator surface states: Role of interface resistance
Connie H. Li, Olaf M. J. van t Erve, Chenhui Yan +2
Current generated spin polarization in topological insulator (TI) surface states due to spin-momentum locking has been detected recently using ferromagnet/tunnel barrier contacts,…
Experimental observation of Dirac-like surface states and topological phase transition in PbSnTe(111) films
Chenhui Yan, Junwei Liu, Yunyi Zang +12
The surface of a topological crystalline insulator (TCI) carries an even number of Dirac cones protected by crystalline symmetry. We epitaxially grew high quality PbSnT…
