Objectives
We propose research to develop a direct writing method that can fabricate and position perovskite nanowires for thermoelectric applications. The key idea is the meniscus-guided approach (Kim et al. 2011) that uses a nano-sized liquid meniscus formed on a glass nanopipette to write materials at nanoscale in ambient condition. The preliminary result proves the liquid meniscus can precisely guide crystallization process at confined region, resulting in millimeter-long, freestanding nanowires at target region. This project consists of (1) the development of fabrication protocol for suspended nanowires and (2) characterization of thermoelectric properties by their direct integration on thermoelectric modules. We expect the project to open an avenue to realize high performance, miniaturized thermoelectric systems for the next generation of renewable green energy.
