Abstract

Las modalidades ilustrativas presentadas en la presente invención se dirigen a un emisor de electrones (22, 22_1, 22_2, 22_3) para un tubo de rayos X. El emisor de electrones comprende un substrato eléctricamente conductor (23) y un material de nanoestructura (24). El material de nanoestructura está compuesto en por lo menos una porción del sustrato eléctricamente conductor. El material de nanoestructura está formado de óxidos, nitruros, siliciuros, seliniuros o telururos. Tal un emisor de electrones se puede utilizar para la emisión híbrida, tal como la emisión de Schottky o emisión de campo.
