Design and evaluation of piezoelectric response in a device based on liquid-phase exfoliated MoS2
Two-dimensional materials have attracted much interest in the last years mainly because when quantum confinement is in place new properties appear.

| description |
Two-dimensional materials have attracted much interest in the last years mainly because when quantum confinement is in place new properties appear. That is the case of single layer or odd layers of MoS2. When confined to 2 dimensions, MoS2 presents new properties, this change is due in part by the loss of centrosymmetry. Additionally, second-order responses appear like second-harmonic generation and piezoelectricity, in the case of MoS2.Then is essential to characterize this type of material in its 2D forms. Our study shows a way to deposit MoS2 using spray coating, and with this process we can study the topology of the MoS2 flakes; we also see the preferred way in which the MoS2 stacks. Two materials were studied, graphene and PMMA, as a possible energy transductor, for piezoelectric measurements, and it was found that in the current configuration graphene does not work as a transductor, and there is need to do further investigation on the PMMA |

Ese es el caso de una sola capa o capas impares de MoS2. Cuando se limita a 2 dimensiones, MoS2 presenta nuevas propiedades, este cambio se debe en parte a la pérdida de centrosimetría. Además, las respuestas de segundo orden aparecen como generación de segundo armónico y piezoelectricidad, en el caso de MoS2. Entonces es esencial caracterizar este tipo de material en sus formas 2D. Nuestro estudio muestra una forma de depositar MoS2 usando un recubrimiento por pulverización, y con este proceso podemos estudiar la topología de los copos de MoS2; También vemos la forma preferida en que se apila el MoS2. Se estudiaron dos materiales, el grafeno y el PMMA, como un posible transductor de energía, para mediciones piezoeléctricas, y se descubrió que en la configuración actual el grafeno no funciona como un transductor, y es necesario investigar más a fondo PMMAFísicoPregrado43 hojasapplication/pdfengUniversidad de los AndesFísicaFacultad de CienciasDepartamento de Físicainstname:Universidad de los Andesreponame:Repositorio Institucional SénecaDesign and evaluation of piezoelectric response in a device based on liquid-phase exfoliated MoS2Trabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPDisulfuro de molibdenoGrafenoPolimetilmetacrilatoTransductores piezoeléctricosFísicaPublicationhttps://scholar.google.es/citations?user=KXWwfMMAAAAJvirtual::7479-10000-0002-6980-8820virtual::7479-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000318566virtual::7479-15ec439ad-c826-485e-8b94-d4fe2bfc1017virtual::7479-15ec439ad-c826-485e-8b94-d4fe2bfc1017virtual::7479-1ORIGINALu831116.pdfapplication/pdf2690421https://repositorio.uniandes.edu.co/bitstreams/e9954f51-265c-4467-911a-4dfd8329c6a7/download6878900c24b5cb049a99d79297cab8b1MD51TEXTu831116.pdf.txtu831116.pdf.txtExtracted texttext/plain61754https://repositorio.uniandes.edu.co/bitstreams/c6caec2d-6d37-4580-a7ba-cf58fd0cbbba/downloadfc11d9fe64b1059369adab4e42c4fd78MD54THUMBNAILu831116.pdf.jpgu831116.pdf.jpgIM Thumbnailimage/jpeg13006https://repositorio.uniandes.edu.co/bitstreams/1e5e76e7-82a2-407e-b9d9-acb5adc597ae/downloadc47730680d95a6919f4fe3fea2859ee0MD551992/44859oai:repositorio.uniandes.edu.co:1992/448592024-03-13 13:26:36.502http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
