The results show that with increasing Cu concentration, martensitic transformation gradually gets close to Curie transition. A magnetostructural transition (MST) is observed in samples with x = 6 and 7. Such MST can enhance magnitude of transformation strain. Besides, Ni50Mn23−xCuxGa27 alloys possess an isotropic, recoverable, and thermally stable thermal strain. Excitedly, Cu doping can effectively tune the phase transition, thermal strain, and thermal expansion properties of Ni50Mn23−xCuxGa27 alloys. Adjustable coefficients of thermal expansion from positive to negative are obtained by Cu‐doped Ni50Mn23−xCuxGa27 alloys. The average linear expansion coefficient (α) between −140.44 and −207.70 ppm K−1 is observed in samples with x = 6 and 7 for a narrow temperature span of 11–14 K. When the temperature span is about 72 K (x = 6) and 73 K (x = 7), which is the largest temperature span observed in Ni–Mn–Ga‐based alloys recently, the α values decrease to about −36 ppm K−1. These findings are beneficial for manipulating the thermal expansion property of Ni–Mn–Ga–Cu alloys and their multifunctional applications.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89788897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the controllable joining of silver nanomaterials has become an effective way to change the electrical and optical properties of silver nanomaterials in recent years. However, urgent research on the controllable joining of silver nanocubes or silver nanocubes is still rarely reported. After being thermal treated at 250 °C for 8 min, a good joining among silver nanocubes can be obtained without significant damage to the cubic structure. For laser sintering, with the increase of laser energy input, silver nanocubes gradually transform to spherical particles. Joining among few particles can be observed when silver nanocubes are scanned by 5 W of laser at 1.0 mm s−1. Obvious joining among silver nanocubes can be obtained by thermal treating at 300 °C for 5 min and laser scanning at 7 W at 0.2 mm s−1. Thermal heating is more suitable for forming different degrees of connection between silver nanocubes or between silver nanocubes, while laser treatment is suitable for changing the shape of silver nanocubes or silver nanocubes without obvious connection.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90949569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the AMO didn't crystallize at 250 °C, but its structure stability increases. When the temperature is 350 and 400 °C, part of the AMO crystallizes into rod‐shaped nano‐α‐MnO2 crystals. At 540 °C, the products crystallize into nano‐α‐MnO2 crystals. Continuing to increase the temperature to 650 °C, the structural stability of the products is further improved. Heat treatment leads to reduced specific surface area and porosity of the material, which in turn leads to reduced specific capacity and cycling stability. In addition, the heat‐treated products show a sharp drop in capacity during the discharge process; this was because the volume change caused by the irreversible phase change of the electrode material is difficult to release in the anisotropic crystal, resulting in the collapse of the structure. This study shows that unheated AMO is better than heat‐treated AMO as a cathode material for aqueous Zn–MnO2 battery cathode material in terms of overall performance and cost.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76176488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sulfur treatment is achieved by mixing sulfur powder with carbon dioxide (CO2) in a reaction chamber under high pressure (3000 psi) at low reacting temperature (120 °C). Based on the experimental results, the SCF sulfur treatment can dramatically change the Ag‐doped SiO2 (Ag:SiO2) thin‐film characteristics, including surface morphology, crystallization, chemical bonding, and mole elements in accordance with the analyses of various materials. In addition, the SCF sulfur treatment is also applied to the Ag:SiO2‐based device to verify the resistance switching (RS) properties. Based on electrical measurement results, the device with the SCF sulfur treatment exhibits better performance. The graduate RS behaviors also exhibit multilevel switching in both set and reset processes, which proves its possible applications of the proposed SCF sulfur treatment. In addition, the current fitting method is used to verify the RS properties to illustrate the carrier transportation characteristics of the Ag:SiO2‐based device with the SCF sulfur treatment.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76213188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The c‐Si cap layer is introduced to increase the photon absorption and hence the enhanced photo carriers increase the overall short‐circuit current. Whereas, the highly doped a‐Si passivation layer reduces the minority carrier flow and recombination at the rear side of the cell, and therefore the passivation layer is used to improve the open‐circuit voltage ( V oc ). The performance optimization and investigation of the cell characteristic is executed using the numerical simulation methodology. To further enhance the cell efficiency, the thickness and doping concentration of the c‐Si cap and a‐Si passivation layer are optimized. The improvement in absorption and passivation quality of the cell leads to the enhancement of 10.54 % in short‐circuit current density and 71.51 % improvement in the V oc , respectively. The designed a‐Si TFSC absorbs the incoming solar spectrum from 300 to 850 nm of wavelength and rest of the spectrum is transmitted. The external and internal quantum efficiency of the cell is well over 95 % . The optimized efficiency of 15.33 % is obtained for the designed cap layered a‐Si passivated cell in AM1.5 G environment using ray‐tracing methodology.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"633 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78980824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
