متن کاملStructural modification of swift heavy ion irradiated amorphous germanium layers
Swift heavy ion (SHI) irradiation of conventional glasses results in non-saturable plastic flow as a consequence of the ion hammering effect [1]. SHI irradiation of amorphous Si (a-Si) at non-perpendicular incidence also leads to unsaturated plastic flow, which shows a linear dependence on the ion fluence. The positive direction of flow suggests that a liquid phase with density similar to that ...
متن کاملMass redistribution causes the structural richness of ion-irradiated surfaces.
We show that the "sputter patterning" topographical instability is determined by the effects of ion impact-induced prompt atomic redistribution and that erosion--the consensus predominant cause--is essentially irrelevant. We use grazing incidence small angle x-ray scattering to measure in situ the damping of noise or its amplification into patterns via the linear dispersion relation. A model ba...
متن کاملEvaporation of ion - irradiated disks
We calculate the evaporation of a cool accretion disk around a black hole due to the ion-bombardment by an ion supported accretion flow (here ISAF, or optically thin ADAF). As first suggested by Spruit & Deufel (2002), this evaporation takes place in two stages: ion bombardment of the cool disk (Shakura-Sunyaev disk: SSD) produces an intermediate-temperature layer on top of the disk ('warm laye...
