dc.description.abstract | Film tipis Barium Titanat didadah Ferrum telah berhasil disintesis
menggunakan metode chemical solution depositioni (CSD) dan teknik spin coating.
Film dibuat dengan mendeposisikan laruta kimia 2M pada substrat Si (100) tipe-p,
lalu diputar menggunakan piringan spin coater pada kecepatan 3000 rpm dalam
waktu 60 detik dan proses pendeposisian ini dilakukan sebanyak 5 kali. Sifat optik
berdasarkan karakterisasi UV-Vis menunjukkan bahwa semakin tinggi konsentrasi
Ferrum di dalam film Barium Titanat (0%; 0,5%; 1%) nilai reflektansinya akan
semakin meningkat dan nilai band gap yang diperoleh menurun dari 2,8 eV – 2,4
eV. Jarak antara fonon optik longitudinal dan optik transversal mengecil seiring
bertambahnya konsentrasi Ferrum. Hasil karakterisasi XRD menunjukkan
parameter kisi yang menurun seiring dengan meningkatnya konsentrasi Ferrum di
dalam film Barium Titanat, karena jari-jarik ionik atom Ferrum (0,77 Å) lebih kecil
dibandingkan jari-jari Barium (1,36 Å). | id |
dc.description.abstract | Fe-doped Barium Titanate thin film in has been successfully synthesized
using chemical solution deposition (CSD) method and spin coating technique. The
film was made by depositing a 2M chemical solution on a p-type Si(100) substrate,
then spin it using a spin coater plate at 3000 rpm for 60 seconds and this deposition
process was carried out 5 times. The optical properties based on UV-Vis
characterization show that the higher the concentration of Ferrum in the Barium
Titanate film (0%; 0,5%; 1%) the reflectance value will increase and the band gap
value decrease from 2,8 eV – 2,4 eV. The distance between the longitudinal and
transverse optical phonons decrease on increasing the concentration of Ferrum. The
XRD characterization results show that the lattice parameters decrease on
increasing Ferrum concentration in the Barium Titanate film, because the ionic
radius of the Ferrum atom (0,77 Å) is smaller than that of Barium atom (1,36 Å). | id |
