Depth-Resolved Evolution of Buried Polar Topologies in a PbTiO3/SrTiO3 Superlattice
Xinxin Hu, Penghan Lu, Noa Varela-Dominguez +9
Polar topologies in complex oxides gives rise to a rich spectrum of emergent functionalities and are fundamentally governed by three-dimensional (3D) atomic structures. However, di…
Complex polar superstructure controlled thermal conductivity in ferroelectric PbTiO3/SrTiO3 superlattices
Noa Varela-Domínguez, Marcel S. Claro, Araceli Gutiérrez-Llorente +8
Integrating epitaxial thin films of ferroelectric PbTiO3 and paraelectric SrTiO3 into artificially layered periodic superlattices provides a unique platform for tuning strain, depo…
Unravelling the Role of Stacking Disorder on the Optoelectronic Properties of Zn3P2
Francesco Salutari, Nico Kawashima, Aidas Urbonavicius +9
Zinc phosphide (Zn3P2) is a promising photovoltaic absorber for thin-film and flexible solar cells due to its earth-abundant composition and favourable optoelectronic properties. R…
Unconventional cross sections in zinc phosphide nanowires grown using exclusively earth-abundant components
Simon Escobar Steinvall, Hampus Thulin, Nico Kawashima +8
To enable lightweight and flexible solar cell applications it is imperative to develop direct bandgap absorber materials. Moreover, to enhance the potential sustainability impact o…
Engineering Ge profiles in Si/SiGe heterostructures for increased valley splitting
Lucas E. A. Stehouwer, Merrit P. Losert, Maia Rigot +6
Electron spin qubits in Si/SiGe quantum wells are limited by the small and variable energy separation of the conduction band valleys. While sharp quantum well interfaces are pursue…
Enhancing atomic-resolution in electron microscopy: A frequency-domain deep learning denoiser
