| description |
La búsqueda de nuevos y mejores materiales multiferroicos está motivada por las posibilidades que ofrecen la sintonización de propiedades magnéticas mediante la aplicación de un campo eléctrico o, viceversa, el control de la polarización eléctrica por campos magnéticos. En la actualidad, la familia de materiales vdW más investigada son los dicalcogenuros de metales de transición (TMD) por exhibir propiedades eléctricas, mecánicas y ópticas prometedoras. Dentro de los TMDs se tienen materiales que bajo ciertas condiciones se ha reportado ferroelectricidad o ferromagnetismo por separado (WTe2, MoS2, MoSe2, WS2, WSe2). En este trabajo, se estudia la variación de las propiedades electrónicas de monocristales de WSe2 a partir de dopaje con Telurio (Te). Como resultado de este dopaje químico, se encontró la presencia en simultáneo de estados ferromagnéticos y ferroeléctricos, es decir, multiferroicidad a temperatura ambiente en el bulk de este material (detectado por primera vez en los TMDs). Monocristales con diferentes niveles de dopaje de Te fueron caracterizados a partir de medidas de XRD, magnetización, microscopía PFM/AMF, y transporte eléctrico. A partir de estas últimas se detectaron propiedades multifuncionales de diodo, suicheo resistivo e histéresis capacitiva. |

En la actualidad, la familia de materiales vdW más investigada son los dicalcogenuros de metales de transición (TMD) por exhibir propiedades eléctricas, mecánicas y ópticas prometedoras. Dentro de los TMDs se tienen materiales que bajo ciertas condiciones se ha reportado ferroelectricidad o ferromagnetismo por separado (WTe2, MoS2, MoSe2, WS2, WSe2). En este trabajo, se estudia la variación de las propiedades electrónicas de monocristales de WSe2 a partir de dopaje con Telurio (Te). Como resultado de este dopaje químico, se encontró la presencia en simultáneo de estados ferromagnéticos y ferroeléctricos, es decir, multiferroicidad a temperatura ambiente en el bulk de este material (detectado por primera vez en los TMDs). Monocristales con diferentes niveles de dopaje de Te fueron caracterizados a partir de medidas de XRD, magnetización, microscopía PFM/AMF, y transporte eléctrico. A partir de estas últimas se detectaron propiedades multifuncionales de diodo, suicheo resistivo e histéresis capacitiva.Ministerio de Ciencia, Tecnología e Innovación de Colombia, through Grant No. 122585271058.
