The resulting material serves as a high-performance\u0000 negative electrode material for lithium-ion batteries.

Traditionally, the improvement of charge transfer efficiency is only limited to the optimization of one or two parameters or the optimization of the working state. In this paper, we propose a more systematic research\u0000 method to optimize the charge transfer efficiency through five aspects: TG channel threshold voltage injection adjustment, PPD N-type impurity injection dose and injection angle, as well as TG operating voltage and FD reset voltage, respectively. The optimal process state and operating\u0000 conditions are obtained: TG channel injection dose of 8.0 e12 cm−2, PPD N-type impurity injection dose of 3.0 e12 cm−2, injection angle of −4°, TG operating voltage of 2.7 V and FD reset voltage of 3.9 V, where the residual\u0000 charge in the signal transfer path is minimal, and the design method in this paper has some guidance for the design of CIS pixels.","PeriodicalId":16446,"journal":{"name":"Journal of Nanoelectronics and Optoelectronics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44589119","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}

The structural and optical properties of the PMMA/TiO2\u0000 NFs before and after γ-irradiation at different doses were analyzed by X-ray diffraction (XRD) and ultraviolet-visible (UV-vis) spectroscopy, respectively. In addition, the impact of γ-dose on the wetting properties of PMMA/TiO2 was determined by measuring\u0000 the water contact angle. The XRD patterns illustrated new sharp peaks after the incorporation of TiO2 nanoparticles (NPs) into the PMMA matrix, which could be due to the interaction of TiO2 with PMMA owing to the change in the crystallographic organization. Moreover,\u0000 the degree of the disorder increases with increasing γ-dose. Optical property studies revealed that the optical gap-band energy of the PMMA/TiO2 dropped to 3.92 eV at the highest γ-dose compared with pure PMMA, which was estimated to be 4.5 eV. A remarkable\u0000 increase in the number of carbon atoms per cluster was observed with increasing γ-dose. The water contact angle was decreased with increasing γ-dose. The decrease in water contact angle is due to the formation of an oxidized layer and/or carbonaceous clusters on the\u0000 surface of the γ-irradiated nanocomposite films. Therefore, it can be concluded that PMMA/TiO2 NFs with controlled optical gap-band energy and controlled water contact angle can be prepared by the γ-irradiation technique to be used for the fabrication of\u0000 optoelectronic products.","PeriodicalId":16446,"journal":{"name":"Journal of Nanoelectronics and Optoelectronics","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44125437","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}
