Synthesis and characterization of BaSnO3 nanomembranes
Abstract/Contents
- Abstract
- Complex oxide materials exhibit a wide range of exotic magnetic, electronic and optical properties, making them attractive candidates for flexible electronics and nanomechanical devices. In addition, these properties are highly tunable by a number of controls such as applied stress, electric fields and temperature. New advances in thin film growth techniques have led to the synthesis of freestanding complex oxide membranes, allowing them to be integrated in flexible and nanomechanical devices. In this work, I will discuss our efforts to fabricate freestanding La-doped BaSnO3 nanomembranes using the water-soluble sacrificial layer Ba3Al2O6. Doped BaSnO3 is a wide band-gap semiconductor that is known to exhibit high electron mobility at room temperature, showing great prospects as an alternative transparent conducting oxide to the industry standard indium-tin-oxide (ITO). In particular, I will discuss the importance of lattice mismatch and internal strain in the sacrificial layer for producing millimeter-scale perovskite oxide nanomembranes with a high degree of crystallinity. I will also discuss our efforts to measure the mechanical properties of BaSnO3 nanomembranes by probing BaSnO3 drumheads with an atomic force microscope. This technique can be used to extract the Young's Modulus and fracture strength of these nanomembranes. These studies provide important context for future studies on manipulating BaSnO3 nanomembranes and their integration into flexible and nanomechanical devices.
