“…In order to reduce the dielectric loss at low frequencies, ZrO 2 was doped into BaTiO 3 to form barium zirconate titanate (Ba(Zr x Ti 1−x )O 3 , short for BZT) [5]. BZT has attracted great attention for its potential applications for the microwave technology [6,7], due to its high dielectric constant, low dielectric loss and large tunability [8].…”

“…This indicates an improvement in the crystalline nature of the film with increase in annealing time duration. According to Cavalcante et al (2007), the growth of granules with the increase of annealing time promotes the reduction of the number of non-bridging oxygen type defects favouring the formation of the ZnO grains. Figure 2 depicts the variation of crystallite size with annealing time.…”

“…The improvement in the structural order may be due to the reduction of nonbridging oxygen type defects, which favours the formation of hexagonal structure (Cavalcante et al 2007). The surface roughness of as deposited and annealed films was also determined.…”

Zinc oxide nanofiber thin films have been deposited on glass substrate by spray pyrolysis technique. The X-ray diffraction studies revealed that the films are polycrystalline with the hexagonal structure and a preferred orientation along (002) direction for films annealed for 1 h at 450°C. Further increase in annealing time changes the preferred orientation to (100) direction. The scanning electron microscopic analysis showed the formation of ZnO nanofiber with an average diameter of approximately 800 nm for annealed films. The compositional analysis of nanofiber ZnO thin films were studied by time of flight secondary ion mass spectroscopy, which indicated oxygen deficiency in the films. The optical properties of annealed films have shown a variation in the band gap between 3.29 and 3.20 eV. The electrical conductivity of the as grown and annealed films showed an increase in the conductivity by two orders of magnitude with increase in annealing duration.

“…Parameter lain yang mempengaruhi lapisan tipis BaZr x Ti 1−x O 3 adalah holding time. Penambahan holding time menyebabkan peningkatan diameter butiran karena dengan peningkatan waktu tahan akan mendorong pengurangan jumlah kerusakan non-bridging oksigen sehingga mendukung pembentukan dari butiran [12].…”

“…Tabel VI menunjukkan seiring dengan bertambahnya holding time maka intensitas semakin tinggi. Bertambahnya holding time maka puncak difransi semakin tinggi pula [12]. Intensitas yang tinggi menunjukkan tingkat kekristalan yang semakin tinggi pula, sehingga dengan penambahan holding time menunjukkan tingkat kristal yang semakin baik.…”

IntisariKajian ini bertujuan untuk mengetahui pengaruh variasi temperatur annealing dan holding time (waktu tahan) terhadap struktur kristal, ukuran partikel, dan ukuran butir lapisan tipis BaZr0,15Ti0,85O3. Penumbuhan lapisan tipis menggunakan metode Chemical Solution Deposition (CSD) atau Sol Gel di atas substrat Pt/Si dengan spin coater. Proses Sol Gel meliputi persiapan sol (koloid), gelation dari sol, dan penguraian pelarut. Penumbuhan lapisan tipis menggunakan variasi temperatur annealing 800 dan 900• C, dan variasi holding time 3 dan 4 jam dengan kecepatan putar 4000 rpm. Lapisan tipis dikarakterisasi dengan XRD dan dilakukan penghalusan menggunakan metode Rietveld dengan program GSAS. Ukuran partikel didapat dengan formula Scherer serta alat SEM untuk mengetahui ukuran butir. Berdasarkan hasil analisis didapatkan bahwa variasi temperatur annealing dan holding time mempengaruhi struktur kristal, ukuran partikel, dan ukuran butir lapisan tipis. Bertambahnya temperatur annealing dan holding time maka parameter kisi semakin besar dengan a = b = c yang berarti memiliki struktur kristal tertragonal. Ukuran partikel semakin besar seiring dengan bertambahnya temperatur annealing dan holding time. Namun, ukuran butir tidak berpengaruh terhadap penambahan temperatur annealing. ABSTRACTThis study purpose to determine the effect of variations of annealing temperature and holding time of the crystal structure, particle size, and grain size on BaZr0,15Ti0,85O3 thin films. Growth of BaZr0,15Ti0,85O3 thin filmsused Chemical Solution Deposition method (CSD) or Sol Gel on the substrate Pt/ Si were prepared by spin coater. These steps the preparation of CSD include sol (colloidal), gelation of the sol, and removal solvent. Growth of thin films using variation of the annealing temperature 800 and 900• CC, and variation of holding time 3 and 4 hours with a rotational speed of 4000 rpm. Thinfilmshave been made then characterized by XRD and refinement performed using the Rietveld method by the GSAS program for to determine the crystal structure. The particle size obtained by Scherer formula and SEM tool to determine the grain size. Based on the analysis it can be concluded that the variation of the annealing temperature and holding time affects the crystal structure, particle size and grain size of the BaZr0,15Ti0,85O3.thinfilm With increasing annealing temperature and holding time the greater the lattice parameters and a = b = c which means it havetertragonal crystalline structure. Particle size greater along with increasing annealing temperature and holding time. However, the annealing temperature variations for the grain size can not be determined.
