Introduction Click to copy section linkSection link copied! Solid oxide-based high-temperature electrochemical devices are expected to play a key role in the future energy landscape, offering efficient and sustainable solutions to the global energy and environmental crisis. (1) Their high-temperature operation, typically above 700 °C, provides unique advantages, including exceptional efficiency, operational versatility, and cost-competitiveness in energy conversion.

Alkylammonium passivation for 2D tin halide perovskite field-effect transistors Tin (Sn) halide perovskites have shown significant potential as channels for field-effect transistors (FETs) due to their low effective mass, reduced Fröhlich interaction, as well as lead-free composition, a requirement for electronic components. However, their inherent instability has limited their practical application.
