Abstract

Las modalidades ilustrativas presentadas en la presente invención se dirigen a un dispositivo para generar rayos X. El sustrato eléctricamente conductor comprende un revestimiento de nanoestructuras (22, 22_1, 22_2, 22_3) que tiene un substrato eléctricamente conductor (23). El sustrato eléctricamente conductor comprende un revestimiento de nanoestructuras (24). El dispositivo además comprende un elemento de calentamiento (21) que se puede conectar a cada sustrato eléctricamente conductor. El dispositivo además comprende un componente de recepción de electrones (14) configurado para recibir los electrones emitidos de por lo menos un emisor de electrones. El dispositivo también comprende un recinto evacuado (10) configurado para alojar el por lo menos un emisor de electrones, el elemento de calentamiento y el componente receptor de electrones. El por lo menos un emisor de electrones se configura para la emisión de Schottky cuando el elemento de calentamiento está en un estado encendido y el por lo menos un emisor de electrones está inclinado negativamente.
