Optical properties of Ta2O5 thin films deposited using the ...

1997-2-28 · Optical properties of tantalum pentoxide thin films have been investigated. The films were prepared by the sol-gel method using the spin coating process. Refractive index and absorption coefficient of the films have been calculated with respect to spinning velocity and number of coating layers from optical transmission measurement in the range ...

Tantalum Pentoxide

Tantalum pentoxide, also known as tantalum (V) oxide, is the inorganic compound with the formula Ta2O5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta2O5 is an inert material with …

Annealing effects on the optical and electrochemical ...

2021-3-21 · Tantalum pentoxide (Ta 2 O 5) has attracted intensive attention due to their excellent physicochemical properties.Ta 2 O 5 films were synthesized via electron beam evaporation (EBE) and subsequently annealed at different temperatures ranging from 300 to 900 °C. X-ray diffraction (XRD) results show that amorphous Ta 2 O 5 thin films form from 300 to 700 °C and then a …

TANTALUM OXIDE DIELECTRICS PROCESSED WITH …

2020-4-1 · Tantalum pentoxide (Ta 2O 5) was sintered with spark-plasma sintering (SPS) using a commercial powder with micometric particles composed of nanometric crystallites. The influence of the SPS process and subsequent annealing on the microstructure, phase composition and dielectric properties was studied.

Tantalum pentoxide

2021-12-28 · tantalum pentoxide film. As the dielectric constant of the tantalum pentoxide is high, the capacitance of a tantalum capacitor is high if the area of the plates is large: where C= capactiance e = dielectric constant A = surface area of the dielectric t = thickness of the dielectric Tantalum capacitors contain either liquid or solid electrolytes.
