The present work focuses on the investigations on the optical and morphological characteristics of (Zr, Mn) co-doped Bismuth ferrite thin films. Undoped Bismuth ferrite (BiFeO ) and (Zr, Mn) co-doped Bismuth ferrite (ZMBFO) thin films were spin-coated on Pt/TiO /Ti/SiO /Si substrate. X-ray diffraction (XRD) was utilized to confirm the rhombohedral structure and the Scherrer formula was used to calculate the crystallite size of the films. The optical properties were explored using UV-visible spectroscopy and the bandgap energies were calculated using a Tauc plot. The surface morphology of the films was explored with the help of atomic force microscopy (AFM) and the three-dimensional (3-D) surface features were determined using stereometric analyses. The variation of 3-D surface parameters was identified to be the consequence of doping.
目前的工作重点是对（锆，锰）共掺杂铋铁氧体薄膜的光学和形态特征进行研究。未掺杂的铋铁氧体（BiFeO₃）和（锆，锰）共掺杂铋铁氧体（ZMBFO）薄膜旋涂在Pt/TiO₂/Ti/SiO₂/Si衬底上。利用X射线衍射（XRD）确认菱面体结构，并使用谢乐公式计算薄膜的微晶尺寸。使用紫外可见光谱探索光学性质，并使用陶克图计算带隙能量。借助原子力显微镜（AFM）探索薄膜的表面形态，并使用立体测量分析确定三维（3-D）表面特征。三维表面参数的变化被确定为掺杂的结果。
