ABSTRAK
Hablur
fotonik menjadi tarikan dalam bidang sains dan teknologi berikutan cirinya yang
unik. Kajian ini bertujuan untuk menentukan struktur jalur hablur fotonik
akibat perubahan saiz nanorod silikon. Kajian dijalankan dengan menggunakan
perisian Bandsolve RSoft. Perisian ini menggunakan pendekatan Plane Wave
Expansion Method (PWEM) bagi
mengira struktur jalur fotonik. Saiz nanorod silikon yang digunakan adalah dari
0.5 μm hingga 0.05 μm. Hasil yang didapati menunjukkan hanya pada
saiz 0.1 μm sehingga 0.4 μm sahaja yang mempamerkan kawasan jalur
terlarang.
Kata
kunci: Hablur fotonik; jalur terlarang; nanorod silikon
ABSTRACT
Photonic
crystals become more attractive in science and technology because of their
unique properties. The objective of this research was to study the effect of
the size of silicon nanorod in the photoni band structure. This research was carried
out by using the RSoft BandSOLVE software.
This software uses the Plane Wave Expansion Method (PWEM) to calculate the band structure of
photonic crystal. The silicon nanorods used in this work ranged from 0.05 μm
to 0.5 μm. The results showed that band structure has a forbidden band for
nanorod with size from 0.1 to 0.4 μm.
Keywords:
Forbidden band; photonic crystals; silicon nanorod
