Quartz Films: Water-Induced Phase Separation Forming Macrostructured Epitaxial Quartz Films on Silicon (Adv. Funct. Mater. 35/2014).

The combination of sol‐gel chemistry and epitaxial growth provides direct access to the integration of piezoelectric macroporous quartz, epitaxially grown on (100)‐silicon substrates. A. Carretero‐Genevrier and co‐workers demonstrate on page 5494 that the interplay between temperature, humidity, catalyst content, and epitaxial growth plays a key role for the bottom‐up fabrication of macroporous quartz on silicon substrates.
