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…
Evidence of a topological Hall effect in EuSmTiO
Kaveh Ahadi, Luca Galletti, Susanne Stemmer
We report on the observation of a possible topological Hall effect in thin films of the itinerant ferromagnet Eu1-xSmxTiO3. EuTiO3 and Eu0.955Sm0.045TiO3 films were grown by molecu…
Response of the lattice across the filling-controlled Mott metal-insulator transition of a rare earth titanate
Honggyu Kim, Patrick B. Marshall, Kaveh Ahadi +3
The lattice response of a prototype Mott insulator, SmTiO3, to hole doping is investigated with atomic-scale spatial resolution. SmTiO3 films are doped with Sr on the Sm site with…
Growth of strontium ruthenate films by hybrid molecular beam epitaxy
Patrick B. Marshall, Honggyu Kim, Kaveh Ahadi +1
We report on the growth of epitaxial Sr2RuO4 films using a hybrid molecular beam epitaxy approach in which a volatile precursor containing RuO4 is used to supply ruthenium and oxyg…
Disorder versus two transport lifetimes in a strongly correlated electron liquid
Patrick B. Marshall, Honggyu Kim, Susanne Stemmer
We report on angle-dependent measurements of the sheet resistances and Hall coefficients of electron liquids in SmTiO3/SrTiO3/SmTiO3 quantum well structures, which were grown by mo…
Negative magnetoresistance due to conductivity fluctuations in films of the topological semimetal Cd3As2
Timo Schumann, Manik Goyal, David A. Kealhofer +1
Recently discovered Dirac and Weyl semimetals display unusual magnetoresistance phenomena, including a large, non-saturating, linear transverse magnetoresistance and a negative lon…
