Processes taking place during hydrogen desorption from MgH2 thin films were investigated in as-prepared samples and samples modified by argon ion irradiation. Irradiation was used to produce well-defined defects with depth distribution. It was shown

In attempt to improve desorption behaviour of MgH2, the influence of well-defined structural changes induced within a thin surface layer of MgH2 have been investigated. The defects were induced by 30 key C2+ ions irradiation using different fluencies

It is well known that optical properties of Mg-Ni-H films can be tuned by hydrogen uptake from Mg-Ni-H and upload into Mg-Ni systems. In this work we show that modulation of optical properties of Mg-Ni-H can take place as a result of thermal processi

This paper deals with non-isothermal kinetics models of hydrogen desorption from MgH2 altered by ion bombardment and stresses the importance of the MgH2 surface during its decomposition. In the case of argon-irradiated samples, where defects are indu
