Abstract The design of the contact surface has a big impact on how well water jets penetrate coal rock. The influence of water jets on contact surfaces with various curvatures is studied using numerical modeling to elucidate the flow field and coal s

XHRTEM observations of different damage structures in high temperature Zn+ implanted GaAs

Autor: Giuseppe Zollo

Publikováno v: Vacuum. 69:97-101

140 keV Zn + ions have been implanted on (1 0 0) GaAs surfaces at a dose of 10 14 cm −2 and different ion fluxes and substrate temperatures. The resulting damage in the implanted samples has been studied by cross sectional high-resolution transmiss
