“…In addition to modifying the bulk, SHI irradiation has been shown to modify the surface morphology of thin films in a variety of systems. [19,20] The type of irradiation ions, synthesis parameters, stoichiometry, and material type, all play an important role in the material's modification. The SHIs move through the material, their bombardment can create disorder in the form of point defects, cluster defects or a perturbed atomic distribution.…”

This study reporting tuning of optical luminescence in Cr‐doped BiFeO3 (BCFO) thin films deposited on glass substrate using spin coater and irradiated with Au+9 (100 MeV) swift heavy ions (SHI) at fluence 1013 ions cm−2. The modification of these thin films has been carried out in its structural and optical properties. An X‐ray diffraction spectra of BCFO thin films confirms rhombohedral perovskite structure with crystallite size distribution of 6–10 nm. Fourier transform infrared (FT‐IR) spectra confirms bonding of Cr in BiFeO3 thin films, however scanning electron microscopy (SEM) images confirm the homogeneous been found to be improved with the band gap tuning in between 2.75 and 2.59 eV via SHI irradiation as per the observations from optical absorption spectra. The purpose of the present study is to synthesize and characterize Cr doped BiFeO3 thin films by a simple spin‐coating method and investigates photovoltaic properties modification due to SHI irradiation for photovoltaic devices.

Swift heavy ion irradiation induced modification of structure and surface morphology of BiFeO3 thin film

BiFeO 3 (BFO) thin films of thickness about 800 nm deposited on Si (100) substrates by sol-gel spin coating method were irradiated by 200 MeV Ag ions. Modification of structure and surface morphology of the films under irradiation was studied using glancing incidence X-ray diffraction (GIXRD) and atomic force microscope (AFM). Fluence dependence of GIXRD peak intensity indicated formation of 10 nm diameter cylindrical amorphous columns in crystalline BFO due to 200 MeV Ag ion irradiation. AFM analysis indicated that the pristine film consists of agglomerated grains with diffuse grain boundary. Irradiation led to reduced agglomeration of the grains with the formation of sharper grain boundaries. The rms roughness (σ rms) estimated from AFM analysis increased from 6•2 in pristine film to 12•7 nm when the film irradiated at a fluence of 1 × 10 11 ions cm −2. Further irradiation led to decrease of σ rms which finally saturated at a value of 7-8 nm at high ion fluences. The power spectral density analysis indicated that the evolution of surface morphology of the pristine film is governed by the combined effect of evaporation condensation and volume diffusion processes. Swift heavy ion irradiation seems to increase the dominance of volume diffusion in controlling surface morphology of the film at high ion fluences.
