As a continuation of a series of exploratory research on preparation of Cu particles and Cu pastes as well as their sinterability as die-attachment materials performed by the authors, this paper presents systematic studies on utilizing an efficient method for preparing bimodal-sized Cu nanoparticles (NPs) and corresponding Cu NP pastes formulated with four types of reducing solvents, and characterizing the air-sintering performance of the Cu pastes subjected to varying process parameters of sintering pressure, temperature and time. Taguchi method analysis shows the shear strength of joints is most influenced by sintering pressure, followed by solvent composition, temperature and time. The novel Cu paste composed of bimodal-sized NPs and glycerol exhibits excellent antioxidant properties, enabling pressureless in-air sintering and bonding. Increase in sintering pressure, temperature and time brings about significantly reduced porosity in the sintered Cu matrix and greatly enhanced shear strength of the joints. After pressureless sintering in air at 280 °C for 10 min, the porosity is 24.3% and shear strength reaches 22.3 MPa; comparatively, increasing pressure to 5 MPa leads to porosity decreasing to 4.1% and strength rising to 70.1 MPa. Increasing pressure and temperature, and prolonging sintering time promote Cu bulk growth and atomic diffusion, thus strengthening the matrix and forming robust interfaces. The above results indicate the great potential of the bimodal-sized Cu NP paste for die attachment in high-power electronic devices under mild sintering conditions.</div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 5","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selenization of stacked precursors is an established procedure for synthesizing (Cu,Ag)2ZnSnSe4 (CAZTSe) thin films. Various process parameters during selenization have been widely researched; however, the availability of selenium quantity during selenization has limited reports and plays a vital role in controlling the film's composition and properties. This study aims to investigate the effect of selenium quantity (100 – 500 mg) during the pre-annealing at 275 °C for 30 min and selenization at 450 °C for 2 min on the structural, morphological, optical, and electrical properties of CAZTSe films. X-ray diffraction (XRD) analysis confirmed a single-phase kesterite structure for films with lower selenium content (≤ 300 mg), while higher selenium content (> 300 mg) led to the formation of secondary SnSe₂ phases. Raman spectroscopy further confirmed the formation of CAZTSe films. Field emission scanning electron microscopy (FESEM) indicated that grain size increased with selenium content, though excessive selenium availability led to surface deterioration. Optical analysis revealed a bandgap increase from 0.99 to 1.12 eV, attributed to the changes in band edges. Electrical measurements showed consistent p-type conductivity, and significant changes in carrier concentration, mobility, and resistivity with increasing selenium content. Therefore, managing appropriate selenium quantity during selenization is crucial for optimizing the process and producing high-quality absorber layers suitable for efficient solar cells.</div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 5","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although SnS2 is a material that possesses two advantages simultaneously, there is no report on its enhancement behavior of photo-assisted capacitance, for the easy recombination with photogenerated charge carriers. Herein, a CuS/SnS2 composite material supported on carbon cloth (CuS/SnS2@CC) was fabricated using a two-step hydrothermal method and tested as a binder-free photo-electrode for photo-assisted electrochemical charge storage applications. The results showed that the construction of a CuS/SnS2 p–n-type heterojunction greatly reduced the recombination efficiency of photogenerated electrons and holes. Consequently, the photo-assisted charging capacity of the electrode increased by 17.4%.
