Why are Compatible CTEs Important in Nanotechnology?
As devices shrink to the nanoscale, the impact of thermal expansion becomes more pronounced. In nanotechnology, materials are often combined to create composites, coatings, or layered structures. If these materials expand or contract at different rates due to temperature changes, it can result in significant stress at the interfaces, causing issues such as delamination, cracking, or warping. Therefore, selecting materials with compatible CTEs is essential to ensure the structural integrity and functionality of nanoscale devices.
