Resumen

La ingeniería, la estabilidad y la orientación de las moléculas semiconductoras son necesarias para lograr la alta eficiencia de los dispositivos multifuncionales de base orgánica. Varias moléculas conjugadas facilitan el uso de campos magnéticos externos para adaptar tanto su orientación molecular como sus propiedades electrónicas mientras se procesan para aplicaciones bio u optoelectrónicas. En este trabajo se investigaron películas moleculares finas de capas de vanadilftalocinina (VOPc) que forman canales conductores en transistores de efecto de campo orgánico. Se desarrollaron tres sistemas basados en una capa fina de VOPc de 100 nm de espesor, uno en ausencia de campo magnético, mientras que los otros dos con paralelos y perpendiculares al plano del sustrato, respectivamente. Los dispositivos fueron investigados ex-situ mediante caracterización eléctrica y espectroscopía Raman de barrido confocal (SRS). El crecimiento de todas las capas moleculares en los electrodos de Au presentó una mejora de la señal de Raman.
