چکیده
The use of water-soluble sacrificial layer Sr$_3$Al$_2$O$_6$ has tremendously boosted the research on freestanding functional oxide thin films, especially thanks to its ultimate capability produce high-quality epitaxial perovskite films. However, costly single-crystalline substrates, e.g. SrTiO$_3$, were generally discarded after obtaining Here, we demonstrate that SrTiO$_3$ substrates can be recycled fabricate La$_{0.7}$Sr$_{0.3}$MnO$_3$ films with nearly identical structural and electrical properties. After attaining residues removed by 80 \degree C hot water soaking rinsing treatments. Consequently, surface reverted original step-and-terrace structure.

متن کاملOrigin of the self-limited electron densities at Al₂O₃/SrTiO₃ heterostructures grown by atomic layer deposition - oxygen diffusion model.
Recently, 2-dimensional electron gas (2-DEG) was discovered at the interface of Al₂O₃/SrTiO₃ (STO) heterostructures, in which the amorphous Al₂O₃ layers were grown by atomic layer deposition (ALD). The saturated electron density at the Al₂O₃/STO heterostructures above the critical thickness of Al₂O₃ is explained by an oxygen diffusion mechanism.

Two soft lithography based fabrication techniques were employed for fabricating mechanically independent, freely suspended polymer microstructure from poly(n-propyl methacrylate) (PPMA) and poly(methyl methacrylate) (PMMA). Both methods involve a micromolding process followed by thermal bonding to the substrate. The first method, sacrificial layer micromolding, uses a water-soluble sacrificial ...

The formation of a two-dimensional electron gas (2-DEG) using SrTiO(3) (STO)-based heterostructures provides promising opportunities in oxide electronics. We realized the formation of 2-DEG using several amorphous layers grown by the atomic layer deposition (ALD) technique at 300 °C which is a process compatible with mass production and thereby can provide the realization of potential applicati...
