Resumo: | Solution processed amorphous metal oxides have been showing competitive electronic performance to the ones produced by vacuum-based techniques, reducing the associated cost. These metal oxides are compatible with a variety of upscaling printing techniques, however, is crucial the optimization of the printing process to obtain stable, reproducible, and high-performance devices. Furthermore, it is important to find alternatives to some of the elements often used (gallium and indium) due to their toxicity and scarcity as well as finding safer solvents to those used in industry. The compatibility with inkjet printing (IJP) of solution processed aluminum oxide (AlOx) (2-methoxyethanol as solvent) and zinc tin oxide (ZTO) using different solvents: ethanol, ethanol (50%).H2O (50%), 1-methoxy-2-propanol (1-MP) and 2 methoxyethanol (2-ME) was performed. Spin-coated ZTO thin film transistors (TFTs) based on ethanol did not show promising results. Spin-coated devices using 1-MP as solvent had decent performance with IOn/IOff ratios of 105 and low subthreshold swing (SS) of 0.66 V.dec-1, however the ink is not compatible with inkjet printing. IJP of 2-ME based ZTO and AlOx thin films was optimized by changing the ultraviolet pre-treatment time, the drops per inch (DPIs), post annealing time, printing speed and number of layers. IJP printed metal-insulator-semiconductor (MIS) capacitors with AlOx based on 2-ME as solvents were printed with one- and two-layers showing breakdown voltages above 1 MV.cm-1. Lastly IJP ZTO/AlOx TFTs based on 2-ME as solvent were achieved with competitive performance showing a mobility of 2.2 cm2.V-1.s-1, a SS of 0.49 V.dec-1 and a IOn/IOff current ratio of 103 on the best devices. The results are the first fully IJP TFTs at CENIMAT/CEMOP and are in accordance with the values typically reported in literature for solution processed ZTO and AlOx, with performance matching devices produced by spin-coating. |

Estes óxidos são compatíveis com variadas técnicas de impressão mas a otimização destes processos é crucial para se obter dispositivos estáveis, reprodutiveis e de alto desempenho. É também importante encontrar alternativas a elementos usados frequentemente como o gálio e indio mas que são raros e/ou apresentam toxicidade, bem como descobrir solventes alternativos mais seguros do que os que são habituais nesta indústria. A compatibilidade com inkjet printing (IJP) de óxido de alumínio (AlOx) (2-methoxyethanol como solvente) e óxido de estanho e zinco (ZTO) usando vários solventes: etanol, etanol (50%).H2O (50%), 1-methoxy-2-propanol (1-MP) e 2-methoxyethanol (2-ME) foi testada. ZTO baseado em etanol depositado por spin-coating não mostrou resultados promissores para aplicação em dispositivos e embora transistores baseados em 1-MP como solvente tenham obtido bons resultados por spin-coating, IOn/IOff ratios de 105 e baixo subthreshold swing de 0.66V.dec-1, a tinta nao mostrou qualquer indicação de ser compatível com inkjet. IJP de ZTO e AlOx baseados em 2-ME como solvente foi otimizado com variação do tempo de tratamentos UV, drops-per-inch (DPI), tratamentos de post annealing, velocidade de impressão e número de camadas. IJP de condensadores MIS (metal-isolante-semicondutor) com AlOx com 2-ME como solvente foram produzidos com uma e duas camadas demonstrando tensões de breakdown suiperiores a 1MV.cm-1. Por último TFTs de ZTO/AlOx produzidos por IJP e baseados em 2-ME como solvente exibiram desempenho copetitivo com mobilidades de 2.2 cm2.V-1.s-1, SS de 0.49 V.dec-1 e currente IOn/IOff de 103 nos melhores dispositivos. Estes são os primeiros TFTs produzidos totalmente por IJP no CENIMAT/CEMOP exibindo valores competitivos com os reportados na literatura para TFTs de ZTO/AlOx de spin-coating processados por solução.Branquinho, RitaCarlos, EmanuelRUNMoreira, Pedro Gabriel2022-08-01T00:31:21Z2022-01-182022-01-18T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/132738enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-03-11T05:11:25Zoai:run.unl.pt:10362/132738Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:47:35.122530Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
