Self-excited instability occurring during the nanoparticle formation in an Ar-SiH4 low pressure radio frequency plasma

This evolution, as well as that of the tetragonality, suggests that the t-STO phase undergoes a progressive tetragonal to cubic phase transition for deposited thicknesses larger than

Optical measurements performed in the plasma center show an evolution similar to the electrical one except near the sharp peak region as observed in [36].. Furthermore, near

The delivery instability is directly linked to the growth of a new generation of dust particles inside the void which trigger strong oscillations of its size. We showed that the

Heartbeat instability for a high repetition rate observed on the dust cloud: (a) some images of the void region (in false colours from dark red to bright yellow) during

Void region in typical dust particle clouds: (a) mixture of grown and injected particles; (b) various sizes of grown particles with crystalline regions and vortex motions (see

In particular perturbations grow in an exponential manner and looking at how their saturation amplitude varies in the (Re, F r) space, we find that an abrupt transition is present

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

A linear stability analysis shows that unstable modulations develop at low and intermediate pressures, following an instability mechanism due to an energy transport effect —
