Research interests

"Toughning by interfacial structuration of thin layers"

I work in the Thin Films and Nanostructures team, and more specifically on pinning and structuration. I study the toughning of low adhesion structured layers deposited by magnetron.

 

Increasing the overall toughening of a stack can be achieved by structuration of thin layers. This interfacial structuration is obtained by using a mask of defined geometry during the sputtering of thin films. It creates areas of high toughness, allowing the pinning of interfacial cracks and resulting in higher overall toughness.

 

Cleavage device for measuring the advance of crack front.
