Abstract
Un fotodiodo (10) PIN que comprende: una primera capa (14) semiconductora tipo p; una capa (18) semiconductora tipo n; una segunda capa (16) semiconductora tipo p dispuesta entre la primera capa (14) semiconductora tipo p y la capa (18) semiconductora tipo n de tal manera que el segundo semiconductor (16) tipo p está directamente adyacente a la capa (18) semiconductora, teniendo la segunda capa (16) semiconductora tipo p una concentración de dopaje graduada; un sustrato (20), creciendo la capa (18) semiconductora tipo n sobre el sustrato (20); una capa (12) de ánodo para recolectar agujeros; una capa (22) de cátodo para recolectar electrones; en el que la concentración de dopaje graduada define una primera concentración (15) adyacente a la primera capa (14) semiconductora tipo p y una segunda concentración (17) adyacente a la capa (18) semiconductora tipo n, y además en el que la primera concentración (15) es mayor que la segunda concentración (17); en el que la luz incidente es absorbida en la segunda capa (16) semiconductora tipo p siendo absorbida la luz incidente en la segunda concentración (17) que es parte de la segunda capa (16) semiconductora tipo p produce electrones y agujeros que derivan al ánodo y cátodo; en el que los electrones generados en la segunda concentración (17) que es parte de la segunda capa (16) semiconductora tipo p alcanzan el cátodo con su velocidad de saturación y son recolectados, los agujeros generados en la segunda concentración (17) que es parte de la segunda la capa (16) semiconductora tipo p se desplazan hasta el ánodo (12), en el que la luz incidente que se absorbe en la primera concentración (15) que es parte de la segunda capa (16) semiconductora tipo p produce electrones y agujeros, en donde los agujeros se recolectan en la primera concentración (15) que es parte; y en el que dichos electrones en la primera concentración (15) que es parte están sujetos a un pseudocampo capaz de proporcionarles una velocidad electrónica de sobreexpansión, siendo regido el pseudocampo por la siguiente ecuación: donde k es la constante de Boltzman, T es la temperatura, q es la carga de un electrón y el valor es el gradiente de concentración de dopaje, y en el que la primera concentración (15) está situada en una posición xo y define una concentración po, y además en el que la concentración de dopaje graduada se rige por la siguiente ecuación: sobre la profundidad D de la segunda capa (16) semiconductora tipo p para todo x y para D mayor que cero.
