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).

Nanocrystalline barium zirconium titanate, BaZr0.4Ti0.6O3, was synthesized successfully via the sonochemical process. The effects of reaction time on the precipitation of Ba(Zr,Ti)O3 particles were investigated briefly. The crystal structure as well as molecular vibrations and morphology were investigated. X-ray diffraction indicated that the powders exhibited a single phase perovskite structure, without the presence of pyrochlore or unwanted phases at the reaction time of 60 min. Nanocrystals were formed before being oriented and aggregated into large particles in aqueous solution under ultrasonic irradiation. A scanning electron microscopy (SEM) photograph showed the BZT powder as spherical in shape with uniform nanosized features.

Mesoporous silica SBA-15 is an interesting material having highly ordered nanopores and large surface area, which is synthesized by sol gel and hydrothermal methods. In this study, mesoporous silica SBA-15 was synthesised with two different methods and the characteris was using X-Ray Diffraction (XRD) and Differential Scanning Calorimetry (DSC). SBA-15 was prepared TEOS as precursor and Pluronic 123 as surfactant. Thermoporous mesoporous DSC thermogram results of the SBA-15A mesoporous silica is (Tg 79oC and Tc 158oC). This is relatively lower than SBA-15B (Tg 86oC and Tc 158oC). The measurement of low angle X-Ray Diffraction SBA-15A has a crystal size 9.46 nm and SBA-15B has a crystal size 9.96 nm. The synthesis of SBA-15 using the hydrothermal method needs to be studied further to obtain thermal characteristics and a more stable crystal structure

This study is conducted to investigate the effect of different annealing temperature on the growth of Silver doped Titanium Dioxide (AgTiO2) nanocrystalline thin films.AgTiO2nanocrystalline thin films on silicon wafer have been prepared by sol–gel spin coating. The thin films were characterized for surface morphology and phase analysis by Scanning Electron Microscope (SEM) and X-ray diffraction (XRD. The films prepared by titanium tetraisopropoxide (TTIP) as the precursor under pH of 3.5 ± 0.5 and with annealing temperature of 300, 400, 500 and 600°C for 2h soaking time. X-Ray diffraction shows that only Ag/TiO2thin film annealed at 600°C have anatase TiO2phase. From SEM micrograph, there are cracks and pulled out thin film from the substrate, which were gradually minimize as the annealing temperature increase.

Carbon Analysis

Telah dilakukan penelitian mengenai pengaruh konsentrasi doping karbon pada lapisan tipis TiO2 yang ditumbuhkan dengan metode spray terhadap struktur kristal dan morfologi TiO2. Hasil karakterisasi SEM menunjukkan bahwa penambahan doping karbon dapat meningkatkan ukuran butir. Lapisan TiO2 doping karbon 8% diperoleh ukuran butir terbesar adalah 1.35 μm, sedangkan ukuran tekecilnya adalah 0.45 μm. Sementara itu, untuk lapisan tipis TiO2 didoping karbon 15% memiliki ukuran butir terbesar yaitu 1.76 μm dan terkecil 0.9 μm. Hasil XRD menunjukkan seluruh puncak difraksi lapisan tipis TiO2 dengan doping karbon 8% dan 15% merupakan TiO2 anatase. Ukuran kristal lapisan TiO2 didoping karbon 8% diperoleh sebesar 638,08 Å dan untuk pendopingan 15% karbon ukuran kristal lapisan tipis TiO2 adalah 638,09 Å, hal ini menunjukkan ukuran kristal kedua sampel tidak mengalami perubahan yang signifikan.   TiO2 thin film with carbon doping has been successfully grown by spray method. The research on the effect of carbon doping on crystal structure and morfology of TiO2 has been prepared by varying carbon concentration (8% and 15% carbon). Analysis of SEM showed that the addition of carbon may increase the grain size. Thin film of TiO2 doped carbon 8% has the largest grain size 1.35 μm, while the smallest grain size is 0.45 μm. Meanwhile, for thin film TiO2 doped carbon 15% has the largest grain size 1.76 μm and smallest 0.9 μm. The XRD results showed the entire diffraction peak of thin film TiO2 doped carbon 8% and 15% were TiO2 anatase. The crystal size of thin film TiO2 doped carbon 8% was obtained at 638.08 Å and for thin film TiO2 doped carbon 15% the crystalline size of TiO2 thin film was 638.09 Å, this shows that the crystal size of both samples did not change significantly.
