Implicit Enthalpy Method for Modelling Laser Induced Melting and Solidification of Silicon
This paper presents a numerical study of laser induced melting and solidification of crystalline Silicon (Si) using an implicit enthalpy method. The simulations are performed using the open source C++ solver known as OpenFOAM [1]. The model considers temperature dependent thermo-physical and optical properties for Si. To verify the numerical model, its predictions are compared with the experime...
متن کاملQuantum Hooke's Law to Classify Pulse Laser Induced Ultrafast Melting
Ultrafast crystal-to-liquid phase transition induced by femtosecond pulse laser excitation is an interesting material's behavior manifesting the complexity of light-matter interaction. There exist two types of such phase transitions: one occurs at a time scale shorter than a picosecond via a nonthermal process mediated by electron-hole plasma formation; the other at a longer time scale via a th...
متن کاملMolecular dynamics studies of ultrafast laser-induced nonthermal melting
Molecular Dynamics (MD) is employed to investigate nonthermal melting triggered by coherent phonon excitation in bismuth telluride, which has Peierls distortion in the lattice structure. Results showed that the structural distortion caused by coherent phonons appears as early as 80 fs, while it takes several picoseconds for the whole phononexcited area to evolve into a liquid state. It was also...

متن کاملPulsed Laser Heating and Melting
Modification of surfaces by laser heating has become a very important aspect of modern materials science. The author’s own interests in laser processing have been involved in the main with laser processing of semiconductors, especially II-VI materials such as CdTe, but also amorphous silicon. Applications of laser processing are diverse and include, in addition to the selective recrystallisatio...
