In this work, we report the realization of a two-dimensional electron gas (2DEG) on the surface of transparent BaSnO₃ via oxygen vacancy creation, which exhibits a high carrier density of ~7.72 × 10¹⁴ cm₋₂ and a high room-temperature mobility of ~18 cm₂·V⁻¹·s⁻¹. Such a 2DEG is rather sensitive to strain and a less than 0.1% in-plane biaxial compressive strain leads to a giant resistance enhancement of ~350% (more than 540 kΩ/□) at room temperature. Thus, this work creates a new path to exploring the physics of low-dimensional oxide electronics and devices applicable at room temperature.]]> Tue 28 Mar 2023 10:08:04 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46764 Mon 06 May 2024 15:37:59 AEST ]]>
