Effect of molar concentration on structural, magnetic domain and optical properties of BiFeO3 thin films

Spray pyrolysis-derived robust ferroelectric BiFeO3 thin films

“…The estimated crystallite size using the strain size plot method is in the range of 16-23 nm, and comparable to the reported results. 15,16,22,23 The slight disparity in the calculated crystallite size values between the two methods arises due to their different assumptions related to strain. Scherrer's method does not consider strain contributions, whereas the strain size plot method does.…”

“…The trend reverses and the thin film annealed for 10 hours shows an increase of optical bandgap to 2.5 eV because of enhanced light scattering arising from increased surface roughness and raptures. 23 From the measured optical data, the skin depth or optical penetration depth which is the distance to which the radiation penetrates can be calculated and shows a decrease with the photon energy (Fig. 4c).…”

Recent advances in bismuth ferrite nanomaterials: Synthesis, characterization and application

“…In general, the reports in the literature focus on preparing thin film materials requiring an deposited surfaces such as LaAlO3, glass and amorphous silica substrates under encompassing various precursors routs [37][38][39][40] . For examples, the chemical vapor deposition 41,42 , pulsed laser deposition 43,44 , sputtering 45,46 , sol-gel process 47,48 and the polymeric 49,50 methods were employ to grow BiFeO3thin films. As displayed in Fig.…”

Influence of two-dimensional oxide nanosheets seed layers on the growth of (100)BiFeO3 thin films synthesized by chemical solution deposition

“…Many different deposition methods have been used to grow BFO thin films including pulsed laser deposition [9,10], chemical vapor deposition [11,12], sputtering [13,14] and chemical solution deposition using the sol-gel process [15,16] or the polymeric precursor method [17,18]. The chemical solution deposition (CSD) consists in the deposition of a solution on a substrate, typically by dip or spin coating, followed by subsequent annealing treatments of the wet film in order to crystallize the desired material [19].…”
