Surface Structures of Epitaxial B20 FeGe(-1-1-1) Thin Films via Scanning Tunneling Microscopy
J. P. Corbett, T. Zhu, A. S. Ahmed +5
We grew 20-100 nm thick films of B20 FeGe by molecular beam epitaxy and investigated the surface structures via scanning tunneling microscopy. We observed the atomic resolution of…
STM and DFT studies of CO2 adsorption on Cu(100)-O surface
Steven J. Tjung, Qiang Zhang, Jacob J. Repicky +5
We characterized CO2 adsorption and diffusion on the missing row reconstructed Cu(100)-O surface using a combination of scanning tunneling microscopy (STM) and density functional t…
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…
