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
