“…Other routes to impose exotic strains, such as ion implantation [210][211][212], and ultrafast optical excitation [213,214], are gaining traction and are uncovering new ways to understand the physics and develop novel functionalities in perovskite oxide films.…”

“…The last type of substrate considered here has been much less studied. Lower symmetry cuts such as ( 210), (310), (211) etc can be used to (i) select specific crystallographic or ferroelectric domains (since they are simply vicinal substrates with larger miscuts), (ii) induce crystallographic tilts to the film structure, and (iii) apply larger strains than conventionally possible, through the partial relaxation of the strain along only one of the in-plane directions. There are relatively few reports of such substrate orientations being used for functional perovskite films (cf table 1).…”

“…This interstitial placement induces strain into the lattice and hence offers a method for so-called strain engineering of a range of physical properties. Very recently, ion implantation using the HIM has been investigated for this purpose, demonstrating the patterning of out-of-plane strain into epitaxial thin films of bismuth ferrite [ 74 ]. In this work, Toulouse et al showed that by continuously varying the dose, continuous elongation of the unit cell in the out-of-plane direction could be achieved, thus enabling fine control over the strain induced.…”

“…to induce changes in nanostructures has started to emerge. For example, scientists inserted helium ions into a crystal lattice by helium ion implantation to create out-of-plane strain into thin films of bismuth ferrite, [19] to produce surface protrusions on the sidewall of micro-disks, [20] to fabricate nano-pyramids on silicon, [21] to produce nano-volcanic nanopores, [22] and to fabricate novel nano-spherical atomic force microscopy (AFM) probes. [23] Here, we demonstrate the capability of directly fabricating unique 3-D silicon structures with surface roughnesses as small as 0.1 nm, such as hierarchical nano-spherical structures, nano-pumpkins, and nano-Taichi symbols, which are very challenging for existing nanofabrication methods.…”

“…[ 18 ] Recently, a new category of using helium ions to induce changes in nanostructures has started to emerge. For example, scientists inserted helium ions into a crystal lattice by helium ion implantation to create out‐of‐plane strain into thin films of bismuth ferrite, [ 19 ] to produce surface protrusions on the sidewall of micro‐disks, [ 20 ] to fabricate nano‐pyramids on silicon, [ 21 ] to produce nano‐volcanic nanopores, [ 22 ] and to fabricate novel nano‐spherical atomic force microscopy (AFM) probes.
