Substrate-dependent pore formation in molybdenum disulfide monolayers under ion irradiation [PDF]

Beilstein Journal of Nanotechnology
Ion irradiation is a versatile tool for nanostructuring surfaces, yet the roles of energy deposition and dissipation at the surface and in ultrathin materials remain poorly understood. In this study, we investigate nanopore formation in monolayer MoS2 on

Reactive sputtering deposition of SiO2 thin films [PDF]

Journal of the Serbian Chemical Society, 2008
SiO2 layers were deposited in a UHV chamber by 1 keV Ar+ ion sputtering from a high purity silicon target, using different values of the oxygen partial pressure (5×10-6-2×10-4 mbar) and of the ion beam current on the target (1.67-6.85 mA).
