Abstrak. Ferroelektrik merupakan bahan yang mempunyai polarisasi spontan serta mempunyai kemampuan mengubah polarisasi internalnya dengan menggunakan medan listrik yang sesuai. Ferroelektrik juga diaplikasikan sebagai kapasitor. Material ferroelektrik buat dalam bentuk film tipis. Barium Zirconium Titanate (BZT) dengan komposisi BaZr0.4Ti0.6O3 dibuat menggunakan metode sol-gel. Substrat yang digunakan yaitu FTO yang telah di etching dan di lapisi BZT serta di annealing pada suhu 800°C selama 2 jam dengan kenaikan laju suhu annealing yaitu 5°C dan 10°C. Sampel di karakterisasi menggunakan XRD. Hasil karakterisasi XRD menunjukkan adanya puncak-puncak yang menandakan terdapat struktur kristal. Struktur kristal yang dihasilkan berada pada bidang 100 pada sudut 2θ = 22.78°, bidang 110 pada sudut 2θ = 32.17°, bidang 111 pada sudut 2θ = 38.42°, bidang 200 pada sudut 2θ = 47.73°. Struktur yang dihasilkan pada penelitian ini yaitu tetragonal dimana a = b = 3.91 nm dan c = 4.05 nm. Laju kenaikan suhu berpengaruh pada puncak Difraksi Sinar-X. Nilai FWHM untuk 5°C lebih kecil dari 10°C, ini menunjukan adanya kerapatan yang lebih besar saat di annealing dengan laju 5°C. Nilai ukuran kristal yang di dapat dengan kenaikan suhu 5°C dan 10°C pada bidang 100 yaitu 3.94 nm dan 3.22 nm. Ukuran kristal berbanding terbalik dengan nilai FWHM dimana laju kenaikan suhu annealing yang kecil menyebabkan ukuran kristal membesar. Abstract Ferroelectrics is a material that has spontaneous polarization and ability to change its internal polarization by using a suitable electric field. Ferroelectricsis also applied as a capacitor. The ferroelectric material is made in the form of a thin film. Barium Zirconium Titanate (BZT) with the composition BaZr0.4Ti 0.6O3 is prepared using the sol-gel method. The substrate used is FTO which has been etched and coated with BZT and annealed at a temperature of 800°C for 2 hours with a increase in the annealing temperature speed of 5°C and 10°C.Samples are characterized using XRD. The XRD characterization results show peaks indicating a crystal structure. The resulting crystal structure is in a plane 100 at an angle of 2θ = 22.78°, a plane 110 at an angle of 2θ = 32.17°, a plane 111 at an angle of 2θ = 38.42°, a plane 200 at an angle of 2θ = 47.73°. The resulting structure in this study is a tetragonal where a = b = 3.91 nm and c = 4.05 nm. The speed at which temperature increases has an effect on the peak of the X-Ray Diffraction.The FWHM value for 5°C is less than 10°C which indicates a greater density when annealed at a speed of 5 °C. The value of the crystal size obtained with an increase in temperature of 5°C and 10°C in the plane 100 is 3.94 nm and 3.22 nm. The crystal size is inversely proportional to the FWHM value where the small speed of the annealing temperature increase causes the crystal size to enlarge.Keywords: BaZr0.4Ti0.6O3 Thin Film, Speed of Annealing Temperature Increase, Sol-gel method, X-Ray Diffraction (XRD).

“…With the development of laser technology, the interaction between laser and matter [1,2], including absorption and reflection of laser energy by target, formation and expansion of plasma, plasma shielding especially prevalent for nanosecond plasma and shock wave effect in the presence of background gas, has become a research hotspot, and gradually formed the research direction and application technology of pulsed laser ablation, such as laser-induced breakdown spectroscopy [3][4][5][6] and pulsed laser deposition [7][8][9]. The plasma produced by laser ablation is transient and inhomogeneous, which can directly affect the accuracy of quantitative analysis and the quality of deposited films.…”

We proposed a theoretical spatio-temporal imaging method, which was based on the thermal model of laser ablation and the two-dimensional axisymmetric multi-species hydrodynamics model. By using the intensity formula, the integral intensity of spectral lines could be calculated and the corresponding images of intensity distribution could be drawn. Through further image processing such as normalization, determination of minimum intensity, combination and color filtering, a relatively clear species distribution image in the plasma could be obtained. Using the above method, we simulated the plasma ablated from Al-Mg alloy by different laser energies under 1 atm argon, and obtained the theoretical spatio-temporal distributions of Mg I, Mg II, Al I, Al II and Ar I species, which are almost consistent with the experimental results by differential imaging. Compared with the experimental decay time constants, the consistency is higher at low laser energy, indicating that our theoretical model is more suitable for the plasma dominated by laser-supported combustion wave.

Ferroelectric is a dielectric material which has spontaneous polarization and has the ability to change its internal polarization using a suitable electric field. The aim of this research is to decrease the FWHM value and increase the crystal size so that the dielectric constant increases for capacitor applications. Thin film ferroelectric material of Barium Zirconium Titanate (BZT) with the composition BaZr0.6Ti0.4O3 was prepared using the sol-gel method. The substrate used was FTO glass which has been treated etching and coated with BZT and in annealing at 800° C with annealing temperature increase of 5°C and 10°C. Samples were characterized using XRD with an angle interval of 2θ between 20° to 60°. The results of XRD characterization show that there were peaks indicating that there was a crystal structure. The resulting crystal structure was in a plane 100 at an angle of 2θ = 22.55°, a plane 110 at an angle of 2θ = 32.00°, a plane 111 at an angle of 2θ = 38.54°, and a plane 200 at an angle of 2θ = 47.64°. The resulting structure in this study was tetragonal where a = b = 3.955 and c = 4.266. The rate at which temperature rose had an effect on the peak of X-Ray diffraction. The FWHM value for 5°C was less than 10°C. This implies a greater density when annealing at 5°C. The crystal size values obtained with an increase in temperature of 5°C and 10°C in the 100 plane were 3.22 and 2.954, respectively. The crystal size was inversely proportional to the FWHM value where the small speed of the annealing temperature increase caused the crystal size to enlarge.
