Probing trade-off between critical size and velocity in cold-spray: An atomistic simulation
Mahyar Ghasemi, Alireza Seifi, Movaffaq Kateb +3
The detailed mechanism of bonding in the cold spray process has remained elusive for both experimental and theoretical parties. Adiabatic shear instability and hydrodynamic plastic…
The role of sputtered atom and ion energy distribution in films deposited by Physical Vapor Deposition: A molecular dynamics approach
Soumya Atmane, Maroussiak Alexandre, Amaël Caillard +4
We present a comparative study of copper film growth with a constant energy neutral beam, thermal evaporation, dc magnetron sputtering, high-power impulse magnetron sputtering (HiP…
OH ions can reduce the iodide migration in MAPI
R. E. Brophy, M. Kateb, I. Ghitiu +6
One of the main degradation mechanisms of methylammonium lead iodine (MAPI), which is an important material for perovskite based solar cells, is the migration of iodide ions. It is…
Epitaxial growth and characterization of (001) [NiFe/M] (M = Cu, CuPt and Pt) superlattices
Movaffaq Kateb, Jon Tomas Gudmundsson, Snorri Ingvarsson
We present optimization of [(15 $\unicode{x212B}$) NiFe/(5 $\unicode{xC5}$) M] single crystal multilayers on (001) MgO, with M being Cu, CuPt and…
Effect of pressure on the dynamics of iodine defects in MAPI: An atomistic simulation
Rachel Elizabeth Brophy, Movaffaq Kateb, Kristinn Torfason +4
The diffusion of iodine defects has been considered the most important degradation mechanism of methylammonium lead iodine (MAPI) in solar cells. The present study demonstrates the…
Distinct melting behaviour of partially oxidized Cu nanoparticles and nanowires
Movaffaq Kateb, Andrei Manolescu
While most of the experimental studies are dealing with partially oxidized metallic nanosolids, their behaviour is not well understood theoretically. To this end we utilized molecu…
