Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

open access: yesAdvanced Science, EarlyView.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Revealing intrinsic strain and domain evolution across the pristine phase transition using PbTiO3 epitaxial films with negligible residual strain [PDF]

open access: yesAPL Materials
Displacive ferroelectrics exhibit a strong coupling between lattice anisotropy and intrinsic structural distortions, and epitaxial constraints in thin films make it essential to directly monitor strain-driven structural responses under controlled ...

Misfit dislocation in a precipitate/matrix interface of any orientation relative to the matrix free-surface

open access: yesArchives of Mechanics, 2020
The presence of an edge dislocation in a surface of a two-dimensional precipitate of square shape embedded in a semi-infinite matrix has been discussed when the precipitate is submitted to misfit strain due to the lattice mismatch between the two phases.

Site‐Specific Hydroxide Formation and Corrosion on Mg Nanocrystals

open access: yesAdvanced Science, EarlyView.
Using single‐crystalline Mg nanocrystals, this study uncovers the intrinsic corrosion initiation mechanism. The stability of the protective Mg(OH)2 film depends on its interfacial coherence with the Mg substrate. Corrosion initiates at exposed corners, where film coverage is incomplete.
