| Summary: | The structural, electrical, and optical properties of zinc oxide (ZnO) was performed using density functional theory using CASTEP software with exchange correlation of generalized gradient approximation (GGA) with Perdew-Burke-Ernzerhof (PBE). The band gap energy of ZnO was observed at 3.27 eV after a Hubbard U correction at energy. Incorporating these corrections brought the band gap energy closer to experimental values. The absorption shows that ZnO fall in the UV region compliment with the band gap energy obtain. |
