Resumo: | The ongoing demand for intelligent, self-sustaining, and multifunction technology, prompts the need to develop environmentally friendly materials, capable of fabricating low cost, recyclable, and flexible electronic components. Printed electronics have emerged as a new technology enabling high cost-efficiency while yielding very promising results, which can be integrated with semiconductor nanostructures. The multicomponent oxide semiconductor zinc-tin oxide (ZTO) is particularly interesting due to its multifunctionality resulting from its excellent electrical and piezoelectrical properties. Moreover, ZTO is a good alternative compared with the most common In-based oxide semiconductors, since it is free of critical elements. This work presents the fabrication of a cellulose-based ink, loaded with ZTO nanostructures, produced via seed-layer free hydrothermal synthesis at only 200 °C. The ink is used for printing a channel between carbon-printed electrodes on paper, using the method of screen printing to produce printed electrolyte-gated transistors on paper, with a cellulose-based ionic conductive sticker as the dielectric. Ink performance was assessed by electrical resistivity measurements, showing a resistivity of the semiconductive layer of 4 MΩ·cm. The electrolyte sticker's great conformability lessens the impact of the channel's surface roughness, resulting in transistors operating with a μSat ≈ 8 cm2·V-1·s-1. This shows how to create reliable, reusable, low-power cellulose-based transistors, ushering in a new age of environmentally friendly "green" electronics |

A eletrónica de impressão surgiu como uma nova tecnologia que permite uma alta relação entre o custo e o benefício, apresentando resultados muito promissores, compatíveis com a integração de nanoestruturas semicondutoras. O óxido semicondutor de zinco e estanho (ZTO) é particularmente interessante devido à sua multifuncionalidade resultante das suas excelentes propriedades elétricas e piezoelétricas. Além disso, o ZTO é uma boa alternativa em comparação com os óxidos semicondutores mais comuns baseados em In, pois é livre de elementos críticos para o ambiente. Este trabalho apresenta a fabricação de uma tinta à base de celulose, com nanoestruturas de ZTO produzidas via síntese hidrotermal a apenas 200 °C. Esta tinta foi impressa com o auxílio de uma tela, entre os elétrodos de carbono, num substrato de papel, formando uma camada semicondutora, e adesivos condutores iónicos à base de celulose foram usados para dielétricos de porta, resultando em transístores eletrólitos em papel. O desempenho da tinta foi avaliado através de medições de resistividade elétrica, mostrando uma resistividade da camada semicondutora de 4 MΩ·cm. A grande confortabilidade do adesivo eletrolítico diminui o impacto da rugosidade da superfície do canal, resultando em transístores que apresentam μSat ≈ 8 cm2·V-1·s-1, mostrando uma abordagem para investigar a aplicabilidade das nanoestruturas para transístores. Isso mostra como criar transístores baseados em celulose, reutilizáveis e de baixo consumo de energia, inaugurando uma nova era de eletrónica "verde" ecológica.Rovisco, AnaBarquinha, PedroRUNDomingos, Bárbara Catarino2023-12-31T01:31:24Z2022-12-122022-12-12T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10362/147196enginfo: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:RCAAP2024-03-11T05:27:58Zoai:run.unl.pt:10362/147196Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:52:44.330506Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
