Hot off the press: new paper in ACS Applied Materials & Interfaces!

The paper “Micro/Nanostructure Engineering of Epitaxial Piezoelectric alpha-quartz Thin Films on Silicon” has been recently published in the journal ACS Applied Materials & Interfaces.

Congratulations to Martí Gich and former N&N Group member Qianzhe Zhang, authors of this work!

This study has been carried out in collaboration with NanoChemLab from Montpellier, France.

Martí Gich has participated in a study published today in Science

altIn this study, authors demonstrate the formation of oriented piezoelectrically active α-quartz thin films directly on silicon. Films are prepared by dip-coating from alcohol/ water solutions of soluble silicic acid precursors plus surfactant or block copolymer structure-directing agents. Solvent evaporation drives the self-assembly of amorphous silica films composed of ordered arrays of pores. An appropriate thermal treatment results on epitaxial quartz films.

We congratulate the authors and specially our group member Martí Gich. You can read the full article
