Glows to Breakdown Characteristic of ZnO Crystal Growth Using Electric Current Heating Method

Abstract

Zinc oxide (ZnO) crystals form are various applications could be created like in manufacturing ultraviolet laser and photodetectors. Zinc oxide (ZnO) crystals are synthesized by applying electric current on ZnO ceramic bar which are made using powder metallurgy method. By using Scanning Electron Microscope (SEM) and X-Ray Diffractometer (XRD) could be characterized of ZnO sintered bars easily. The different types of crystal are produced such as polygonal, broken stick, flowers, trunks and many more when applied the DC heating until the sample of ZnO will be glows and breaks apart. The loads or pressure and heating method to the sample of ZnO will be affected to the types of crystal growth. The optimum load is 3 metric tonne and will ease the ignition during DC heating due to less porosity of the samples.
