Hopping motion of a particle along a substrate driven by a surface acoustic wave

Marina Terzi, Vladislav Aleshin, Jules Ghesquiere

Manipulation of small objects (particles) lying on vibrating or acoustically excited substrates is of interest for a number of applications such as micro-positioning or acoustic cleaning of surfaces. The objective is to provide a stable directed motion of a particle along a surface supporting a...

Pinces acoustiques hautes fréquences pour la manipulation d'objets micrométriques

Jean-Louis Thomas, Michael Baudoin, Roudy Al Sahely

Les pinces acoustiques sont l’équivalent des pinces optiques, elles utilisent un faisceau focalisé pour piéger en trois dimension un objet à l’aide de la pression de radiation. Ces dernières ont permis de faire des manipulation d’objets micro-métrique avec une précision nano-métrique. Néanmoins une...

Surface oxidation and oxygen incorporation in ScAlN films grown by molecular beam epitaxy

Valentina Gallardo-Mödinger, Frédéric Georgi, Xavier Wallart, Ileana Florea, Philippe Vennéguès, Yvon Cordier, Maxime Hugues

Recently, there has been much interest in the ScAlN alloy, thanks to its various potential applications in high-frequency high-power, acoustoelectric, and ferroelectric devices. Nonetheless, these applications could be impaired by the presence of oxygen in the alloy and the formation of a surface...
