摘要： A photoelectric device having at least a predetermined impurity region which is disposed in a semiconductor substrate, and a photoelectric conversion portion which is constructed by stacking an electrode layer lying in contact with at least a part of the impurity region, a photoconductive material layer overlying the electrode layer, and a transparent electrode overlying the photoconductive material layer, characterized in that the photoconductive material layer is made of an amorphous chalcogenide material which principally contains Se, is disclosed. It is very favorable that the photoelectric conversion material layer made of the amorphous material principally containing Se is partially doped with Te so as to enhance its sensitivity. The amorphous chalcogenide material is very useful in the following point. In the course of forming, or after having formed, at least one photoconductive layer on a semiconductor body whose surface is uneven, a heat treatment is performed at a temperature of at least the softening point of the photoconductor so as to flatten the layer, whereby discontinuous parts of the photoconductor ascribable to the uneven surface of the semiconductor body can be avoided.

摘要： The present invention relates to a method and an apparatus for driving image pick-up tubes in, particular, a color television camera or the like having more than one image pick-up tube and in particular to a method and an apparatus for driving image pick-up tubes in which the potentials of the cathode electrodes of the respective image pick-up tubes are set to the same common potential, the potential of the target electrode of at least one of the image pick-up tubes is set substantially to earth potential, target drive potentials are individually applied to the target electrodes of the other image pick-up tubes, and the target potential of each image pick-up tube is set to a value near the earth potential, so that a high S/N ratio is obtained. The driving appartatus can be miniaturized and easily driven. According to the invention, a capacitor, such as a chip capcitor or the like, with a low withstanding voltage can be used in a first-stage amplifier to amplify the video signal from the target electrode. This first-stage amplifier can be arranged near a signal output electrode of the target. Thus, the stray capacitance can be reduced.
