Gradient induced liquid motion on laser structured black Si surfaces
I. Paradisanos, C. Fotakis, S. H. Anastasiadis +1
This letter reports on the femtosecond laser fabrication of gradient-wettability micro/nano- patterns on Si surfaces. The dynamics of directional droplet spreading on the surface t…
Ripple formation on Nickel irradiated with radially polarized femtosecond beams
George D. Tsibidis, Evangelos Skoulas, Emmanuel Stratakis
We report on the morphological effects induced by the inhomogeneous absorption of radially polarized femtosecond laser irradiation of nickel (Ni) in sub-ablation conditions. A theo…
From ripples to spikes: a hydro-dynamical physical mechanism to interpret femtosecond laser induced self-assembled structures
George D. Tsibidis, Costas Fotakis, Emmanuel Stratakis
Materials irradiated with multiple femtosecond laser pulses in sub-ablation conditions are observed to develop various types of self-assembled morphologies that range from nano-rip…
Intense femtosecond photoexcitation of bulk and monolayer MoS2
I. Paradisanos, E. Kymakis, C. Fotakis +2
The effect of femtosecond laser irradiation on bulk and single-layer MoS2 on silicon oxide is studied. Optical, Field Emission Scanning Electron Microscopy (FESEM) and Raman micros…
