Printed insulating interlayrs
Olejníková, Marie ; Zmeškal, Oldřich (referee) ; Dzik, Petr (advisor)
This bachelor thesis deals with preparation and study of printed insulating interlayers based on barium titanate. The composition of ink formulation and method of deposition were investigated. The composition was optimised with the type of added binder. The printing was made using a screen printing method. Characterisation of prepared layers was made using contact profilometry and optical microscopy. Dielectric properties of layers were subsequently analysed using the impedance spektroskopy method.

Dielectric layers fabricated by material printing
Olejníková, Marie ; Pekárková, Jana (referee) ; Dzik, Petr (advisor)
This master‘s thesis deals with the use of the material printing method for fabrication of dielectric films. Final high- dielectric composite film consisted of BaTiO3 based inkjet-printed layer and spin-coated polyvinylpyrrolidone (PVP) layer. The effect of ball-milling on BaTiO3 suspension was studied by DLS a XRD methods. Printing formulation and parameters of inkjet printing were optimized with respect to the surface morphology of printed BaTiO3 films using contact profilometry method. Impedance analysis was used to determine the value of effective dielectric constant of the final dielectric composite film using thin film capacitor structure. Effective dielectric constant of composite dielectric film was 4,9 ± 0,4.
