Point group symmetry of cadmium arsenide thin films determined by convergent beam electron diffraction
Honggyu Kim, Manik Goyal, Salva Salmani-Rezaie +4
Cadmium arsenide (Cd3As2) is one of the first materials to be discovered to belong to the class of three-dimensional topological semimetals. Reported room temperature crystal struc…
Basal-plane growth of cadmium arsenide by molecular beam epitaxy
David A. Kealhofer, Honggyu Kim, Timo Schumann +3
(001)-oriented thin films of the three-dimensional Dirac semimetal cadmium arsenide can realize a quantum spin Hall insulator and other kinds of topological physics, all within the…
Electron nematic fluid in a strained Sr3Ru2O7 film
Patrick B. Marshall, Kaveh Ahadi, Honggyu Kim +1
Sr3Ru2O7 belongs to the family of layered strontium ruthenates and exhibits a range of unusual emergent properties, such as electron nematic behavior and metamagnetism. Here, we sh…
Spontaneous Hall effects in the electron system at the SmTiO3/EuTiO3 interface
Kaveh Ahadi, Honggyu Kim, Susanne Stemmer
Magnetotransport and magnetism of epitaxial SmTiO3/EuTiO3 heterostructures grown by molecular beam epitaxy are investigated. It is shown that the polar discontinuity at the interfa…
Two-Dimensional Dirac Fermions in Thin Films of Cd3As2
Luca Galletti, Timo Schumann, Omor F. Shoron +4
Two-dimensional states in confined thin films of the three-dimensional Dirac semimetal Cd3As2 are probed by transport and capacitance measurements under applied magnetic and electr…
Observation of the quantum Hall effect in confined films of the three-dimensional Dirac semimetal Cd3As2
Timo Schumann, Luca Galletti, David A. Kealhofer +3
The magnetotransport properties of epitaxial films of Cd3As2, a paradigm three-dimensional Dirac semimetal, are investigated. We show that an energy gap opens in the bulk electroni…
