Finite element analysis of the initial stages of the laser ablation process
J.C. Conde,Fernando Lusquiños,Pío González,Julia Serra,Betty León,A. Dima,L. Cultrera,D. Guido,A. Zocco,Alessio Perrone +9 more
TL;DR: In this article, the initial stages of the laser ablation process have been investigated considering the surface roughness and the continuous morphological changes of the surface produced by laser irradiation, and a computational approach of the structure formation on the irradiated surface by finite elements using ansys ® (6.1) has been developed.

Pulsed laser deposition and characterization of textured Pd-doped-SnO2 thin films for gas sensing applications
Antonio Pereira,L. Cultrera,A. Dima,M. Susu,Alessio Perrone,H.L. Du,A.O. Volkov,R. Cutting,Psantu K. Datta +8 more
TL;DR: In this paper, Pd-doped-SnO 2 thin films were grown on Si (100) substrates using pulsed laser deposition at room temperature, and the morphologies depend therefore on the O 2 pressure, since by increasing the pressure from 10 to 100 Pa the film morphology changes from a cracked structure to a well developed cauliflower-like structure with a columnar growth.

Detailed studies of the plume deflection effect during sub-ps laser ablation of Si target
A. Dima,Alessio Perrone,A. Klini +2 more
TL;DR: In this paper, the plume deflection effect during the irradiation of silicon target with sub-ps KrF laser pulses was investigated in vacuum with different laser fluences and number of pulses.

Double-peak droplet mass distribution observed during sub-ps laser ablation of Si targets
TL;DR: In this paper, the angular distribution of the ablated material was studied during sub-ps Si laser ablation deposition using a special hemicylindrical substrate holder and different laser fluences ranging between 0.4 and 1.7 J/cm2.
SnO2 nanostructured films obtained by pulsed laser ablation deposition
Carmen Ristoscu,L. Cultrera,A. Dima,Alessio Perrone,R. Cutting,H.L. Du,A. Busiakiewicz,Z. Klusek,Psantu K. Datta,S.R. Rose +9 more
TL;DR: In this paper, the authors used a XeCl * laser to ablate a tin oxide target either in vacuum or in an atmosphere containing a relatively low partial pressure (10 � 2 to 100 Pa) of O2.
