Electric Field Effects on Curved Graphene Quantum Dots Huerta Sainz, Sergio de la Ballesteros Castañeda, Ángel Cordero Tejedor, Nicolás A. Graphene Nanoflake Electric field Quantum revival DFT The recent and continuous research on graphene-based systems has opened their usage to a wide range of applications due to their exotic properties. In this paper, we have studied the effects of an electric field on curved graphene nanoflakes, employing the Density Functional Theory. Both mechanical and electronic analyses of the system have been made through its curvature energy, dipolar moment, and quantum regeneration times, with the intensity and direction of a perpendicular electric field and flake curvature as parameters. A stabilisation of non-planar geometries has been observed, as well as opposite behaviours for both classical and revival times with respect to the direction of the external field. Our results show that it is possible to modify regeneration times using curvature and electric fields at the same time. This fine control in regeneration times could allow for the study of new phenomena on graphene. 2023-12-19T08:56:08Z 2023-12-19T08:56:08Z 2023-12-19T08:56:08Z 2023-10 info:eu-repo/semantics/article 2072-666X http://hdl.handle.net/10259/8220 10.3390/ mi14112035 eng Micromachines. 2023, V. 14, n. 11, 2035 https://doi.org/10.3390/mi14112035 info:eu-repo/grantAgreement/AEI/Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020/PGC2018-097831-B-I00/ES/FENOMENOS CRITICOS, SIMETRIA Y FASES TOPOLOGICAS EN SISTEMAS CUANTICOS/ http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional MDPI
