Beyond Structural Stabilization of Highly‐Textured AlN Thin Films: The Role of Chemical Effects

Advanced Materials Interfaces, Volume 11, Issue 25, September 3, 2024.
Metallic seed layers with low work function promote the growth of c‐axis oriented, crystalline AlN thin films. This study shows that the effect is predominantly structure‐agnostic and can be linked to a nitrogen termination of the seed metal layers prior to the AlN growth.
