Laser printing of azo-derivative thin films for non-linear optical applications

Investigations on laser printing of microcapacitors using poly (methyl methacrylate) dielectric thin films for organic electronics applications

“…This phenomenon is probably related to the viscous properties of the PMMA solution, an effect also observed in reference [32]. In Figure 5b, one may clearly notice that the impact of printing ejects a small amount of polymeric material sideways, hence assuring the electrical separation of the two electrodes [6][7][8][9]. First, the values of the capacitance were experimentally measured for standardized capacitors and then compared to the theoretical value, calculated using the parallel capacitor approximation:…”

“…laser-induced forward transfer (LIFT), has been thoroughly investigated and presented in literature as an excellent spatially resolved printing method for organic and inorganic materials, in solid or liquid form [3]. Cutting and printing can be done by direct irradiation, with the use of an additional protecting layer made of a metal [3,[4][5][6][7], a polymeric sacrificial film [3,[8][9][10][11], i.e. a dynamic release layer (DRL) [3,8,12,13], or by using a specially designed printing system, i.e.…”

Octahydroacridine thin films grown by matrix-assisted pulsed laser evaporation for non linear optical applications

“…As a final aspect of our work, we have to take into consideration that the chemical structure, the crystalline state, and thus the homogeneity of the sample, all play a very important part in its SHG capabilities [49].I ti sa l s ow o r t h mentioning that, for the thin films, the thickness, but also the surface morphology, plays an important role in the SHG intensity [50][51][52][53][54][55].…”
