2. Comparative Analysis with Alternative Materials

Comparing MgO (111) substrates against materials like sapphire or spinel shows magnesium oxide’s lower bulk density and higher thermal conductivity can be advantages in specific applications. While sapphire is known for its hardness, MgO offers a more compatible thermal expansion coefficient for particular metal-oxide semiconductor films. This can minimise stress at elevated temperatures, reducing substrate cracking or film delamination.

Merging mechanical strength with chemical resistance, MgO (111) substrates can withstand a range of processing conditions without contamination or corrosion. Many alternative materials may require additional treatment steps to maintain stability, which can increase production costs. In such cases, magnesium oxide’s resilience and ease of integration often make it the preferred substrate for thin-film research and device fabrication.
