| Abstract Scope |
Freestanding oxide membranes transform 3D materials into tunable quasi-2D platforms that enable the exploration and deliberate design of novel stacked materials. Thus, integrating more devices per unit area, i.e., ‘More Moore’ and achieving multifunctionalities within a smaller volume, i.e., ‘More than Moore,’ can be envisioned for the next generation of microelectronics, such as energy-efficient AI hardware and in-memory computing. In this work, we will present a recent progress on developing twist perovskite-oxide membranes and moiré materials based on various interfacial terminations that alter drastically the physical properties. Dielectric (SrTiO3) and magnetic (SrRuO3) membranes are among the examples and will be presented to show how twisting could yield highly tunable novel electronic structures and chiral magnetism, respectively. Furthermore, a synthetic approach to create large-scale membranes with precision polymer deconstruction will be presented, highlighting our new fabrication strategy in creating atomically thin, crack-free, and large-scale oxide membranes. |
