“…By the end of the simulation, t = 30 ps, clusters are formed with different sizes. This atomistic point of view is comparable to what have been done for the general case in Lennard-Jones material [8]. As can be seen from the figure, after the energization, the nanoparticle temperature is homogenized throughout the system.…”

“…The energy that is deposited into the system in the beginning of the simulation is responsible in forming this clusters. Within this simulation, where energy absorbed by the system is 1.5 eV/atom, the nanoparticle is fragmented into several big clusters, while for even higher energization the system tend to boil up and bigger cluster cannot survived [8].…”

“…Molecular dynamics simulation has been done for the case of thin film [2][3][4][5][6], Lennard-Jones nanoparticles [8] also the comparison between these two forms [9]. While for the case of smooth energization, such as two-temperature model, the energy transferred from the electronic to the atomic system have been done in bulk [10,11] and thin film [5,12].…”

We investigate ablation of Aluminum nanoparticle due to ultrashort high-intensity laser pulse. Molecular dynamics simulation is used to follow the evolution of the system and observe thermodynamics together with cluster properties. The energy given from the laser to the system is 1.5 eV/atom which is above ablation threshold and modelled using instantaneous and homogenous energization at the beginning of simulation. The evolution of the system shows a highly non-equilibrium state after the irradiation. Expansion of the sphere indicated that the system cannot survive from the temporary high tensile pressure that leads to ablation. While the high temperature consecutively responsible for the formation of cluster, it also indicated that the system is relaxed at the end of the simulation.

“…In the context of thermal properties, it is interesting to observe the behavior of thin film corresponds to its thickness. In a way where heating could be done in a short time scale, it will gives information on the phase transition of the thin film, such as effected by ultrashort laser irradiation [2,3].…”

We investigated the influence of Aluminum thin film thickness during heat treatment. The films with thickness of 5 nm, 10 nm and 15 nm were heated from room temperature up to above melting point with same heating rate. Molecular Dynamics (MD) simulation is employed to study the behaviour of the thin film where the atoms were followed based on its trajectories. Thin film thickness gives significance contribution to the mechanism of the melting. Smaller thickness suffered strong pressure oscillation while the thin film temperature is increases. Local crystal structure confirmed the transformation of the system from crystalline state to melting state.

“…MD simulation could provide atomistic point of view of structural change since it follows the trajectory of the atoms within the simulation. In the general case where Lennard-Jones material is considered to shows the evolution of laser induced structural change of nanoparticle and thin film, Fahdiran and Urbassek [4,5] used MD simulation to show the small-angle scattering structural change due to heat absorbed from the laser. The results show that MD simulation could give insight into the material, especially the structure of the system.…”

We study the structural change of Aluminum thin film due to heat treatment. The film is heated up from room temperature of 300 K to 1000 K where it is already above melting temperature of Aluminum. Molecular dynamics simulation is employed to observe the behavior of the system since it provides atomistic detail. The structural transformation is investigated based on the structure factor and pair distribution function which indicated the broadening of the peak of crystal structure due to phase transition of the material. Atomistic information revealed the local lattice structure change based on Common Neighbor Analysis (CNA) methods.
