Strain Dependent Characterization of Flexible BaSnO<sub>3 </sub>Nanomembranes

ORAL

Abstract

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. Flexible transparent conducting oxides are of special interest for future photonics and optoelectronic devices but realizing high-quality films as flexible materials has been a challenge. In this work, we will discuss our efforts to fabricate nanometer thick, freestanding La-doped BaSnO3 film that are highly conducting and transparent using a water-soluble and lattice matched Ba3Al2O6 buffer layer1. Using this technique, we can transfer the nanomembranes onto a flexible device platform and characterize the physical and electronic properties of La-doped BaSnO3 as a function of strain.
