ABSTRACT

 

Co-synthesis of In2O3 and ZnO nanowires (NWs) were grown on silicon and alumina substrates using vapour transport deposition method. Their morphological structures showed that the NWs were rather aligned on silicon substrate and randomly oriented on alumina substrate. The formation of NWs on silicon substrate was found to be dominated by the growth of ZnO NWs while that on alumina substrate was dominated by the growth of In2O3 NWs. The In2O3 and ZnO NWs were highly crystalline and have wurtzite structure.

 

Keywords: Co-synthesis; In2O3; nanowires; ZnO

 

ABSTRAK

 

Sintesis bersama bagi nanowayar In2O3 dan ZnO telah ditumbuhkan ke atas substrat silikon dan alumina menggunakan kaedah pemendapan wap. Struktur morfologi menunjukkan bahawa nanowayar tumbuh dengan agak teratur di atas substrat silikon manakala secara rawak pada substrat alumina. Penumbuhan nanowayar di atas substrat silicon didominasi oleh nanowayar ZnO, manakala di atas substrat alumina didominasi oleh nanowayar In2O3. Nanowayar In2O3 dan ZnO mempunyai kualiti kristal yang agak tinggi dan berstruktur wursit.

 

Kata kunci: In2O3,; nanowayar; sintesis bersama; ZnO
