Here we report, independently, about the impact of subsequent annealing and the influence of additional hydrogen incorporation on these films, which should lead to a further enhancement of TC. However, the expected TC increase was not observed, on the contrary, both annealing of films at 800 °C in vacuum and incorporation of hydrogen into these films led to a reduction of TC. Analysis of the results shows that in case of annealing this is related to nitrogen release from the films, in case of hydrogenation to reductions of the density of states at the Fermi level and of the electron-phonon interaction.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"161 ","pages":"Article 107851"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143161869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BFO/MWCNTs nanocomposites with varying weight percentages of multi-walled carbon nanotubes (MWCNTs), specifically with x = 0, 5, 10, 15, and 20 wt%, were prepared using the ultra-sonication method. Toluene was employed as a functionalization agent to enhance the dispersion. Various characterization techniques, including X-ray diffraction (XRD), Transmission electron microscopy (TEM) and Raman spectroscopy, as well as dielectric and magnetic property measurements were conducted to comprehensively analyze the prepared nanocomposites. XRD analysis confirmed the crystalline structure of the nanocomposites. Scherrer's formula calculated the crystallite size based on the major plane peak in XRD patterns, which revealed a range of 45 nm–50 nm. TEM micrographs showed the morphology, dispersion and interaction of nanoparticles with MWCNTs. The Raman spectroscopy was utilized to reveal the phonon modes of the nanocomposites. The dielectric response was investigated in a wide range of frequencies ranging from 1 MHz to 3 GHz and observed a significant change with the addition of MWCNTs. Vibrating sample magnetometery (VSM) analysis was conducted under magnetic fields ranging from −20 to 20 KOe. The magnetic constraints such as saturation magnetization (Ms), coercivity (Hc), remanent magnetization (Mr), squareness (Mr/Ms) and anisotropic constant (K) have decreased with the increasing content of the MWCNTs. The high dielectric and low magnetic properties make these nanocomposites suitable for energy and data storage applications.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"160 ","pages":"Article 107800"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present work, BBPDs were fabricated employing simple spin coated thin films (TFs) of Cd(1-x)AgxS colloidal quantum dots (CQDs), where x = 0.0 to 0.05. The x-ray diffraction (XRD) patterns of TFs confirm the formation of a cubic phase with a crystallite size very close to Bohr's atomic radius. The existence of microstructural defects like twinning/multiple twinning was confirmed by HRTEM images of the undoped and 3 wt% Ag-doped CdS QDs. The spectral tunability along with modifications in detector characteristic parameters were observed with varying concentrations of Ag. The maximum value of various performance parameters like sensitivity (S), responsivity (R), detectivity (D), and external quantum efficiency (EQE) were estimated as ∼ 1.95 × 104 %, 14.67 A/W, 4.84 × 1012 cmHz1/2W−1, and 3.8 × 103 %, respectively. Besides, the response speed of PD was also improved by twofold due to the insertion of Ag. The fastest PD responds within 104 ms (rise time)/98 ms (fall time). The present work demonstrates BB spectral (405 nm–845 nm) detection by Cd(1-x)AgxS CQDs-based PDs and tunability in the selectivity and detectable wavelength with variation of Ag dopant. The device S3 is the fastest and demonstrated the highest S and D among all devices under 782 nm illumination; however, S1 is optimised for PD in the present study as it delivered the best performance in the said BB spectral region with a reasonably good response speed of 200 ms.</div></div>","PeriodicalId":432,"journal":{"name":"Solid State Sciences","volume":"160 ","pages":"Article 107805"},"PeriodicalIF":3.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
