Optimization of the growth conditions of Cu₂O thin films and subsequent fabrication of Cu₂O/ZnO heterojunction by m-SILAR method

Facile synthesis of Cu 2 O nanorods in the presence of NaCl by successive ionic layer adsorption and reaction method and its characterizations

“…Likewise, the surface resistivity, the activation energy followed the same trend, and the values were found to be 0.14–0.21 eV. The measured values were perfectly matched with the reported results [ 24 , 37 ], and in this study, the sample deposited with 4 mmol NaCl electrolyte exhibited the lowest resistivity and activation energy as well as well-distributed nanorods. Hence, the sample S4 has preferentially shown better quality than the other deposited Cu 2 O samples.…”

“…There are various methods to synthesis Cu 2 O thin films such as atomic layer deposition [15], electrochemical deposition [16][17][18][19], metal-organic chemical vapour deposition [20], molecular beam epitaxy [21], successive ionic layer adsorption and reaction (SILAR) [22][23][24], the direct oxidation of Cu sheets [25], sputtering [26], vapour phase epitaxy [27] and sol-gel technique [28]. However, towards the preparation of nanostructured Cu 2 O, the electrodeposition of Cu 2 O thin films allows the greatest control yet [23][24][25][26]. To the best of our knowledge, there is no study about the SILAR deposition of Cu 2 O nanorod films until now.…”

“…In this study, a modified SILAR method was used to synthesize Cu 2 O nanostructured thin films. In our prior report, we have shown the modification [22][23][24] of SILAR by eliminating the rinsing steps during the growth of pure Cu 2 O thin films and named the method as the modified (m)-SILAR technique. Therefore, we synthesized Cu 2 O nanorods on SLG substrates by the m-SILAR method in the nominal presence of NaCl into the precursor solution complex.…”

Copper oxide nanostructured thin films processed by SILAR for optoelectronic applications

“…36 To justify further the effects of CH 3 COOH and rinsing steps, Farhad and co-workers again deposited thin lms at pH 4.50-7.95 by adding CH 3 COOH into cationic precursor solutions. 37,101 It is seen that lm deposited without any rinsing step showed the lowest band gap due to the high lm thickness and vice versa which is shown in Fig. 7(a).…”

Green synthesis of ZnO nanoparticles usingCocos nuciferaleaf extract: Characterization, antimicrobial, antioxidant, and photocatalytic activity

“…There are a lot of applications of ZnO in engineering, biological, and medicinal fields. ZnO NPs have several engineering applications such as in solar cells [8–10], gas sensors [11], chemical sensors [12], biosensors [13], and photodetectors [14], whereas, in biological and medicinal applications, ZnO NPs have cytotoxic activity [15], antimicrobial and fungicidal activities [16], anti-inflammatory activity, capability to quicken wound healing, antidiabetic [17, 18], and chemiluminescent properties [19, 20].…”
