Nanoscroll formation from strained layer heterostructures
TLDR
In this paper, the authors model the strain relaxation using continuum strain theory and predict that the scroll diameter depends on the winding direction if the cubic symmetry of zinc blende semiconductors is taken into account, 〈100〉 being the preferred winding direction.Abstract:
Nanoscrolls develop when thin, strained semiconductor multilayers are peeled off from their substrate. We model the strain relaxation using continuum strain theory and predict that the scroll diameter depends on the winding direction if the cubic symmetry of zinc blende semiconductors is taken into account, 〈100〉 being the preferred winding direction. The effects of nonlinear strain and third order elastic coefficients are considered, the latter leading to smaller scroll diameter.read more

Strain induced semiconductor nanotubes: from formation process to device applications
TL;DR: Semiconductor nanotubes (SNTs) represent a new class of nanotechnology building blocks as mentioned in this paper, which are formed by a combination of bottom-up and top-down approaches, using strain induced self-rolling mechanism from epitaxially grown heterojunction films.

Semiconductors turn soft: inorganic nanomembranes
Francesca Cavallo,Max G. Lagally +1 more
TL;DR: In this article, the authors presented single-crystal Si in a new fashion, i.e., as a form of soft matter, if fabricated as flexible nanomembranes, and suggested a plethora of interesting science and many applications that may benefit from the use of Si in this soft matter form.

Membrane folding to achieve three-dimensional nanostructures: Nanopatterned silicon nitride folded with stressed chromium hinges
TL;DR: In this paper, the concept of folding nanopatterned membranes into 3D shapes is referred to as nanostructured origami because of the similarity to the Japanese paper-art of origami, where two-dimensional surfaces are folded into volumetric shapes.

Formation mechanism of TiO2 nanotubes
TL;DR: In this paper, it was shown that single-layer TiO2 sheets were formed by rolling up the single layer sheets with a rolling-up vector of [001] and attracting other sheets to surround the tubes.

Extensions of the Stoney formula for substrate curvature to configurations with thin substrates or large deformations
TL;DR: In this paper, the curvature-strain relastionship was derived for cases in which the Stoney formula relating substrate curvature to mis-match strain in a bonded thin film was relaxed, providing a biasis for interpretation of experimental observations for a broader class of film-substrate configurations.
