The effect of Fe addition on γ′ precipitates during thermal exposure in Ni-Co-based single crystal superalloys

open access: yesJournal of Materials Research and Technology, 2022
The effect of Fe addition on γ′ precipitates in Ni–20Co-xFe-12Cr-7.5Al-7.5Ti-1.5 W (where x = 0 or 4 at.%) single crystal superalloys during thermal exposure process was systematically studied.

The Effect of Lattice Misfit on Deformation Mechanisms at High Temperature [PDF]

open access: yesAdvanced Materials Research, 2011
Understanding the relationship between deformation mechanisms and microstructure is essential if one wants to fully exploit the potential of advanced nickel base superalloys and develop future alloys. In the present work, the influence of the lattice misfit between  and ’ has been studied by means of in-situ loading experiments using neutron ...

Structure of CdTe/ZnTe superlattices [PDF]

open access: yes, 1987
The structure of CdTe/ZnTe superlattices has been analyzed through θ/2θ x‐ray diffraction, photoluminescence, and in situ reflection high‐energy electron diffraction (RHEED) measurements.

Systematic {\em ab initio} study of the phase diagram of epitaxially strained SrTiO$_3$

open access: yes, 2006
We use density-functional theory with the local-density approximation to study the structural and ferroelectric properties of SrTiO$_3$ under misfit strains. Both the antiferrodistortive (AFD) and ferroelectric (FE) instabilities are considered.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications. [PDF]

open access: yesAdv Mater
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Effect of the lattice misfit on the equilibrium shape of strained islands in Volmer-Weber growth

open access: yes, 2010
We have studied the effect of the misfit on the equilibrium shape of three-dimensional pyramidal islands grown on a foreign substrate in the case of incomplete wetting (Volmer-Weber mode of growth).

Intertwined chiral charge orders and topological stabilization of the light-induced state of a prototypical transition metal dichalcogenide [PDF]

open access: yes, 2019
The fundamental idea that the constituents of interacting many body systems in complex quantum materials may self-organise into long range order under highly non-equilibrium conditions leads to the notion that entirely new and unexpected functionalities ...

First-principles study of epitaxial strain in perovskites

open access: yes, 2005
Using an extension of a first-principles method developed by King-Smith and Vanderbilt [Phys. Rev. B {\bf 49}, 5828 (1994)], we investigate the effects of in-plane epitaxial strain on the ground-state structure and polarization of eight perovskite oxides:

Morphological instability, evolution, and scaling in strained epitaxial films: An amplitude equation analysis of the phase field crystal model [PDF]

open access: yes, 2010
Morphological properties of strained epitaxial films are examined through a mesoscopic approach developed to incorporate both the film crystalline structure and standard continuum theory.
