Effect of Pyrolysis Temperature on Sol-Gel Synthesis of Lead-free Piezoelectric (K,Na)NbO3
 Films on Nb:SrTiO3
 Substrates

ABSTRACTTwo sol-gel processes for producing Pb1-xBaxTiO3 (PBT), a ferroelectric material of interest for sensor and actuator applications, are investigated. Each system incorporates lead nitrate and barium acetate as metal sources and ethylene glycol as a solvent. Diethanolamine is used as a chelating agent for titanium isopropoxide or titanium butoxide. Precursor chemistry was systematically varied and the resulting sols and powders were studied using TGA/DSC, FTIR, and XRD. Thin films were prepared using both precursor sources by spin coating onto single crystal (100) MgO. Spin speed and pyrolysis temperature were optimized to produce oriented thin films with thicknesses of up to approximately 500nm. Sols incorporating titanium isopropoxide and a large excess of diethanolamine were particularly stable against hydrolysis.

Sol Gel Synthesis

AbstractReal 3-D sub-νm lithography was performed with two-photon polymerization (2PP) using inorganic-organic hybrid polymer (ORMOCER®) resins. The hybrid polymers were synthesized by hydrolysis/polycondensation reactions (modified sol-gel synthesis) which allows one to tailor their material properties towards the respective applications, i.e., dielectrics, optics or passivation. Due to their photosensitive organic functionalities, ORMOCER®s can be patterned by conventional photo-lithography as well as by femtosecond laser pulses at 780 nm. This results in polymerized (solid) structures where the non-polymerized parts can be removed by conventional developers.ORMOCER® structures as small as 200 nm or even below were generated by 2PP of the resins using femtosecond laser pulses. It is demonstrated that ORMOCER®s have the potential to be used in components or devices built up by nm-scale structures such as, e.g., photonic crystals. Aspects of the materials in conjunction to the applied technology are discussed.
