 Research of Interests: My field is studying both the induced surfaces' random kinetic morphology and the self-organization of nanoscale surfaces pattern formations by the board ion beam. I am working on the modelling calculations, experimental findings, and simulation results.

 Research Area: Ion-induced modification and Nanostructuring of non-equilibrium Surfaces, Numerical Solution of time-domain PDEs with Noise, and Renewable Energy.

 Sputtering a solid surface with an ion beam of relatively low energy (order of a few kilo electron volts) can result not only in surface kinetic roughening but also in the self-organization of ordered quasi-periodic nanostructures, such as ripples, dots, and holes under appropriate conditions, as shown in the figure below.

 The outcomes of these results will enhance theoretical understanding of non-equilibrium surface patterning, ultimately aiming to quantitatively predict the wavelength of quasi-periodic structures and tune their structural coherence for potential applications in diverse fields such as anti-reflective surfaces for solar cells, optoelectronics, and data storage.

Images of ion-induced self-organized nano-patterns surface (i.e., ripples, dots, and holes) obtained by computational modelling of their governing PDEs such as Makeev, Cuerno and Barabasi (MCB) continuum model with/without noise as shown below.

The computational solutions of the height surface, h(x,y,t) as shown in the images are made by Mogtaba Mekki.
