A novel superstructure in epitaxially grown 1T-TaTe
Jinwoong Hwang, Yeongrok Jin, Canxun Zhang +13
The spontaneous formation of electronic orders is a crucial element for understanding complex quantum states and engineering heterostructures in two-dimensional materials. We repor…
Large-gap insulating dimer ground state in monolayer IrTe2
Jinwoong Hwang, Kyoo Kim, Canxun Zhang +11
Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of…
Chemical Migration and Dipole Formation at van der Waals Interfaces between Magnetic Transition Metal Chalcogenides and Topological Insulators
Brenton A. Noesges, Tiancong Zhu, Jacob J. Repicky +5
Metal and magnetic overlayers alter the surface of the topological insulator (TI) bismuth selenide (BiSe) through proximity effects but also by changing the composition and…
Coherent Growth and Characterization of van der Waals 1T-VSe Layers on GaAs(111)B Using Molecular Beam Epitaxy
Tiancong Zhu, Dante J. O'Hara, Brenton A. Noesges +7
We report epitaxial growth of vanadium diselenide (VSe) thin films in the octahedrally-coordinated (1T) structure on GaAs(111)B substrates by molecular beam epitaxy. Film thick…
Magnetic Properties and Electronic Structure of Magnetic Topological Insulator MnBiSe
Tiancong Zhu, Alexander J. Bishop, Tong Zhou +12
The intrinsic magnetic topological insulators MnBiX (X = Se, Te) are promising candidates in realizing various novel topological states related to symmetry breaking by magn…
Importance of Paramagnetic Background Subtraction for Determining the Magnetic Moment in Epitaxially Grown Monolayer and Few-Layer van der Waals Magnets
Dante J. O'Hara, Tiancong Zhu, Roland K. Kawakami
Due to the atomically thin nature of monolayer and few-layer van der Waals magnets, the undesired background signal from the substrate can have significant contribution when charac…
Topological Dirac Semimetal Na3Bi Films in the Ultrathin Limit via Alternating Layer Molecular Beam Epitaxy
Igor V. Pinchuk, Thaddeus J. Asel, Andrew Franson +6
Ultrathin films of Na3Bi on insulating substrates are desired for opening a bulk band gap and generating the quantum spin Hall effect from a topological Dirac semimetal, though con…
Room Temperature Intrinsic Ferromagnetism in Epitaxial Manganese Selenide Films in the Monolayer Limit
Dante J. O'Hara, Tiancong Zhu, Amanda H. Trout +9
Monolayer van der Waals (vdW) magnets provide an exciting opportunity for exploring two-dimensional (2D) magnetism for scientific and technological advances, but the intrinsic ferr…
Molecular beam epitaxy growth of SrO buffer layers on graphite and graphene for the integration of complex oxides
Adam Ahmed, Hua Wen, Taisuke Ohta +4
We report the successful growth of high-quality SrO films on highly-ordered pyrolytic graphite (HOPG) and single-layer graphene by molecular beam epitaxy. The SrO layers have (001)…
