“…It has been used in a variety of applications such as: (a) fabrication of high density bio-microarrays for site selective binding of proteins, 31 (b) processing of biological surfaces, (c) self-assembled structuring and chemical reactions and (d) modification of the surface hardening due to enhanced glassification or carbonization of the irradiated areas. 32 In addition, by selecting appropriate matrices containing silicon atoms, the morphological modifications at 157 nm 32,33 should induce major cross-transport phenomena 34 and entropic variations within the nanoensembles.…”

“…Scission of polymeric bonds at 157 nm is followed by formation of new bonding. Additional processes such as stacking of photo dissociated moieties on the surface, formation of pillars, self assembly, volume or surface ablation, etc, [22] are tailoring further the surface functionality. The processes show such a degree of complexity, exhibiting spot size dependence [23].…”

A KrF excimer laser with wavelength of 248nm and pulse width of 22ns was irradiated on rotating sintered BaZr x Ti 1-x O 3 (BZT) (x=0.00, 0.25, 0.50, 0.75, 1.00) target at fluence of 3.0J/cm 2 and pulse frequency of 2Hz. The single layer BZT films were deposited on Nb-doped SrTiO 3 (111) substrate at temperature of 973K in O 2 -8%O 3 atmospheric gas pressure of 0.1, 1 and 8Pa. The BZT super lattice films were also fabricated at same conditions of single layer BZT films. The films were oriented to (111) direction. The 2-theta peak position of BZT (111) decreased as the x value increased. In the case of x>0.5, the dielectric constant was hardly changed by atmospheric gas pressure. The dielectric constant of the BZT solid solution film decreased as x value increases. In the case of x<0.5, the dielectric properties were different at each atmospheric gas pressure. The temperature dependences of dielectric constant in BZT film at 100mPa and 1Pa were almost constant, however the film at 8Pa was not stable. The oxygen pressure influenced dielectric properties in particular composition region (x=0.25) where relaxor phenomenon existed.

“…F 2 excimer lasers are also used for the modification of sol-gel derived amorphous Al 2 O 3 thin films at ambient temperature; this results in a change of the film from hydrophilic to hydrophobic [18]. Surface functionalization is wavelength dependent [19], and VUV irradiation of polymeric surfaces induces major morphological and chemical changes [20,21].…”

Sol–gel tetramethoxyorthosilicate (TMOS) derived composite thin films comprising embedded NiCl2 nanoparticles, were illuminated and processed by 193 and 157 nm excimer laser radiation. The effect of different laser fluences of 193 nm and the number of 157 nm pulses on the material surface was studied. Atomic force microscopy imaging was used to evaluate the effects of the irradiation. It was found that surface morphology was modified in a controllable way, with physical and chemical properties strongly depending on the illumination conditions. Ablative ultraviolet laser surface processing is a generic single-step approach that can be applied successfully in composite materials. Applications involve micro/nanostructure formation for use in hybrid photonic and optoelectronic devices and other applications.
