    Efek Variasi Suhu Annealing Terhadap Morfologi Nanotube ZnO yang Di-doping Boron
    (2016-01-30) Pajrin, Erawati; Iwantono; Umar, Akrajas Ali
    ZnO nanotube growth onto Florine Tin Oxide (FTO) was successfully carried out by the hydrothermal method. The effect of annealing temperature was evaluated using several methods : Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-Ray (EDX). The FESEM images showed ZnO nanotubes with a slighty different size of diameter grown on the substrate. The EDX study confirmed the presence of Zn shown by the three peaks of 1 keV, 8.60 keV, and 9.60 keV, while the presence of B was confirmed by the peak of 0.16 keV. The EDX also informed physically quantified percentage of Zn and O are representiedly the weight percentage of 71.22 % and 3.72 % and atomic percentage of 35.40 % and 11.18 %.
