Femtosecond Laser Crystallization of Ultrathin a-Ge Films in Multilayer Stacks with Silicon Layers
Yuzhu Cheng, Alexander V. Bulgakov, Nadezhda M. Bulgakova +3
Ultrashort pulsed laser annealing is an efficient technique for crystallizing amorphous semiconductors with the possibility to obtain polycrystalline films at low temperatures, bel…
Coherence effects in LIPSS formation on silicon wafers upon picosecond laser pulse irradiations
Inam Mirza, Juraj Sládek, Yoann Levy +7
Using different laser irradiation patterns to modify of silicon surface, it has been demonstrated that, at rather small overlapping between irradiation spots, highly regular laser-…
Dual-wavelength femtosecond laser-induced low-fluence single-shot damage and ablation of silicon
Alexander V. Bulgakov, Juraj Sládek, Jan Hrabovský +3
A study of damage and ablation of silicon induced by two individual femtosecond laser pulses of different wavelengths, 1030 and 515 nm, is performed to address the physical mechani…
On the Melting Thresholds of Semiconductors under Nanosecond Pulse Laser Irradiation
J. Beranek, A. V. Bulgakov, N. M. Bulgakova
In this work, a unified numerical model is used to determine the melting thresholds and to investigate early stages of melting of several crystalline semiconductors (Si, Ge, GaAs,…
Melting of gold by ultrashort laser pulses: Advanced two-temperature modeling and comparison with surface damage experiments
Sergey A. Lizunov, Alexander V. Bulgakov, Eleanor E. B. Campbell +1
The ultrafast laser-induced solid-liquid phase transition in metals is still not clearly understood and its accurate quantitative description remains a challenge. Here we systemati…
Cluster Generation Under Pulsed Laser Ablation Of Compound Semiconductors
Alexander Bulgakov, Anton Evtushenko, Yuri Shukhov +2
A comparative experimental study of pulsed laser ablation in vacuum of two binary semiconductors, zinc oxide and indium phosphide, has been performed using IR-and visible laser pul…
