Material de banda intermedia basado en un compuesto semiconductor de tipo calcogenuro de estaño

Abstract

Material de banda intermedia basado en un compuesto semiconductor de tipo calcogenuro de estaño. La invención se refiere a compuestos formados mediante la introducción, dentro de un semiconductor de partida que es de tipo calcogenuro de estaño tetravalente octaédricamente coordinado, de un elemento de transición en posición octaédrica, para la fabricación de materiales o dispositivos para aplicaciones fotónicas. El elemento de transición genera una banda intermedia parcialmente ocupada separada de las de valencia y conducción del semiconductor de partida, según resulta de cálculos mecanocuánticos. Esto posibilita obtener, por absorción de dos fotones de energía inferior a la anchura de la banda prohibida del semiconductor de partida, un resultado equivalente al que se consigue absorbiendo un fotón de energía superior a dicha anchura en ausencia de banda intermedia.
