Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement. [PDF]

Adv Mater
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Effect of the segmented fin height on the air-side performance of serrated welded spiral fin-and-tube heat exchangers

Case Studies in Thermal Engineering, 2022
Serrated welded spiral fin-and-tube heat exchangers (SWSFTHXs) are experimentally investigated. The work primarily focuses on the effects of the segmented fin height (hs) with various fin pitches (fp) on the air-side performance (ASP).
