Abstract
Because of their superior optical, and electrical properties, lead halide perovskites have emerged as potential materials for light-emitting-diodes. However, some obstacles have yet to be overcome for practical applications including low exciton binding energy, the difficulty of fabricating uniform perovskite films,, and their instability to heat, light, and moisture.

Korean J. Met. Mater. 2016;54(10):759-767. Published online 2016 Oct 5
DOI: https://doi.org/10.3365/KJMM.2016.54.10.759

Abstract
In this study, the effect of cold drawing and heat treatment on the microstructure of Invar36 alloy wire was investigated. Invar36 alloy wire is used as a transmission line core material, and is required to have high strength. The diameter of the Invar36 alloy wire specimens were reduced from 16..... More
