En este trabajo se presenta evidencia experimental de generación resonante de fotocorriente en materiales fotoconductores periódicamente nanoestructurados y sensibilizados con un colorante. Esta propiedad se logra mediante el uso de estructuras periódicas preparadas alternando capas de diferente índice de refracción o bien creando una capa más gruesa en la mitad de la estructura cuyos modos fotónicos localizados son controlados espectralmente de manera que coincidan o no con la banda de absorción del colorante. Los resultados son explicados a través del cálculo de la distribución espacial de la intensidad de campo eléctrico en las configuraciones antes detalladas.

Herein we show experimental evidence of resonant photocurrent generation in dye sensitized periodically nanostructured photoconductors, which is achieved by spectral matching of the sensitizer absorption band to different types of localized photon modes present in either periodic or broken symmetry structures. Results are explained in terms of the calculated spatial distribution of the electric field intensity within the configurations under analysis.
