Abstract
Perfeccionamientos en dispositivos semiconductores que comprenden una pluralidad de capas de material semiconductor unidas a tope de un tipo de conductividad opuesta alterna, cuyas capas se agrupan en una secuencia de pares de capas, caracterizados porque el espacio de banda de la primera capa y el espacio de banda de la segunda capa en cada par de dicha secuencia son virtualmente iguales, los espacios de banda de cada par de dicha secuencia se disponen en una secuencia de tamaños en reducción y la segunda capa de por lo menos un par de la secuencia se adultera ligeramente.
