Abstract
The invention relates inter alia to a photoconductor (10) comprising a multilayer (13) which comprises a plurality of photoconductive semiconductor layers (131-134). According to the invention, the multilayer (13) comprises at least two sublayers (130) which each comprise at least a first photoconductive semiconductor layer (131) and a second photoconductive semiconductor layer (132), wherein the first and the second photoconductive semiconductor layer (131, 132) are doped to different degrees for each of the sublayers (130).
Claims15
A photoconductor having a layer package comprising a plurality of photoconductive semiconductor layers, wherein
- the layer package comprises at least two sub-packages, each comprising at least one first photoconductive semiconductor layer and a second photoconductive semiconductor layer,
- wherein in each of the at least two sub-packages the at least one first photoconductive semiconductor layer and the second photoconductive semiconductor layer are doped to different degrees,
- wherein
- a dopant or dopants with which the first and second semiconductor layers are doped is or are iron, rhodium or ruthenium and wherein in each of the at least two sub-packages, due to the doping to the different degrees
- each of the at least one first photoconductive semiconductor layer has a greater recombination rate for electron-hole pairs than the second photoconductive semiconductor layer and
- in each of the at least two sub-packages, due to the doping to the different degrees, the second photoconductive semiconductor layer has a greater electrical resistance than the first photoconductive semiconductor layer.
