Perspective: strain and strain gradient engineering in membranes of quantum materials [PDF]
Appl. Phys. Lett. 122, 170501 (2023), 2023 Strain is powerful for discovery and manipulation of new phases of matter; however, the elastic strains accessible to epitaxial films and bulk crystals are typically limited to small ($<2\%$), uniform, and often discrete values. This Perspective highlights new directions for strain and strain gradient engineering in free-standing single crystalline ...

Nonsingular stress and strain fields of dislocations and disclinations in first strain gradient elasticity [PDF]
arXiv, 2005 The aim of this paper is to study the elastic stress and strain fields of dislocations and disclinations in the framework of Mindlin's gradient elasticity. We consider simple but rigorous versions of Mindlin's first gradient elasticity with one material length (gradient coefficient).

Strain-gradient mediated local conduction in strained bismuth ferrite films. [PDF]
Nat Commun, 2019 It has been recently shown that the strain gradient is able to separate the light-excited electron-hole pairs in semiconductors, but how it affects the photoelectric properties of the photo-active materials remains an open question.

Strain Gradient Elasticity in SrTiO3 Membranes: Bending versus Stretching.
Nano letters (Print), 2021 Young's modulus determines the mechanical loads required to elastically stretch a material and also the loads required to bend it, given that bending stretches one surface while compressing the opposite one.

Higher order nonlocal strain gradient approach for wave characteristics of carbon nanorod
Nonlinear Analysis, 2014 In this paper an attempt is made to study the wave dispersion characteristics of a carbon nanorod through second, fourth, sixth and eighth order nonlocal strain gradient models. Expressions are derived for both wave number and wave speeds of the nanorod.
