The origin of insulating and non-ferromagnetic SrRuO3 monolayers
Zeeshan Ali, Zhen Wang, Andrew O'Hara +5
The electro-magnetic properties of ultrathin epitaxial ruthenate films have long been the subject of debate. Here we combine experimental with theoretical investigations of (SrTiO3…
Visualizing quantum phenomena at complex oxide interfaces: an atomic view from scanning transmission electron microscopy
Hangwen Guo, Mohammad Saghayezhian, Zhen Wang +3
Complex oxide interfaces have been one of the central focuses in condensed matter physics and material science. Over the past decade, aberration corrected scanning transmission ele…
Fermions and bosons in nonsymmorphic PdSb2 with sixfold degeneracy
Ramakanta Chapai, Yating Jia, W. A. Shelton +6
PdSb2 is a candidate for hosting 6-fold-degenerate exotic fermions (beyond Dirac and Weyl fermions).The nontrivial band crossing protected by the nonsymmorphic symmetry plays a cru…
Role of disorder and correlations in metal-insulator transition in ultrathin SrVO3 films
Gaomin Wang, Zhen Wang, Meng Meng +7
Metallic oxide SrVO3 represents a prototype system for the study of the mechanism behind thickness-induced metal-to-insulator transition (MIT) or crossover in thin films due to its…
Surface and Interface Properties of La2/3Sr1/3MnO3 Thin Films on SrTiO3 (001)
Lina Chen, Zhen Wang, Gaomin Wang +6
Understanding and manipulating properties emerging at a surface or an interface require a thorough knowledge of structure-property relationships. We report a study of a prototype o…
Unusual Fe-H bonding associated with oxygen vacancies at the (001) surface of Fe3O4
Fangyang Liu, Chen Chen, Hangwen Guo +6
An unusual Fe-H bonding rather than conventional OH bonding is identified at Fe3O4 (001) surface. This abnormal behavior is associated with the oxygen vacancies which exist on the…
