Understanding insulating ferromagnetism in LaCoO3 films under tensile strain
Ali Barooni, Murod Mirzhalilov, Mohit Randeria +2
LaCoO3 thin films grown under epitaxial tensile strain exhibit a robust ferromagnetic insulating state that is absent in the bulk. Despite many studies, both experimental and compu…
Towards dislocation-driven quantum interconnects
Cunzhi Zhang, Victor Wen-zhe Yu, Yu Jin +4
A central problem in the deployment of quantum technologies is the realization of robust architectures for quantum interconnects. We propose to engineer interconnects in semiconduc…
A common origin of photoplastic and electroplastic effects in ZnS
Alexandra Fonseca Montenegro, Sevim Genlik Polat, Md Mohsinur Rahman Adnan +2
Dislocation motion--the atomic-scale mechanism of crystal plasticity--governs the strength and ductility of materials. In functional materials, external stimuli beyond mechanical s…
Photoluminescence excitation spectroscopy of quantum wire-like dislocation states in ZnS
Alexander Blackston, Alexandra Fonseca Montenegro, Sevim Polat Genlik +2
Recent \textit{ab initio} calculations predict 1D dispersive electronic bands confined to the atomic scale cores of dislocations in the wide bandgap (3.84 eV) semiconductor ZnS. We…
The Origin of Photoplasticity in ZnS
Sevim Polat Genlik, Roberto C. Myers, Maryam Ghazisaeidi
ZnS is a brittle material but shows extraordinary plasticity during mechanical tests performed in complete darkness. This phenomenon is known as the photoplastic effect, whose unde…
Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from Strain-induced Spin-State Transition
Menglin Zhu, Joseph Lanier, Sevim Polat Genlik +7
Creating new interfacial magnetic states with desired functionalities is attractive for fundamental studies and spintronics applications. The emergence of interfacial magnetic phas…
