fotokonduktorin

Fotokonduktorin is a German term that functions as the feminine form of Fotokonduktor. It can refer to a photoconductor, a material whose electrical conductivity increases when it is illuminated, or, less commonly, to a woman who works with or studies photoconductive materials. The underlying concept is photoconductivity, where light absorption generates charge carriers (electrons and holes) that enhance conductivity.

In photoconductors, conductivity depends on light intensity and the material’s properties. When dark, many photoconductors are relatively insulating; exposure to light creates electron–hole pairs, boosting current flow. Some materials exhibit fast, reversible responses, while others show persistent or wavelength-specific effects. The choice of material determines sensitivity, speed, and spectral response.

Historically, photoconductors played a central role in xerography and electrophotography. Early photoreceptors used selenium, with later advances including inorganic compounds such as cadmium sulfide and zinc oxide, and more recently organic photoconductors. In imaging and sensing technologies, photoconductive layers enable charged-pimage formation and photodetection without requiring photovoltaic power generation. Today, photoconductors are found in various devices, including copy machines, imaging sensors, and certain photodetectors, each selected for specific spectral response and electrical requirements.

Notes: In German-language usage, Fotokonduktorin can denote either a female scientist or engineer working with photoconductive materials or, less commonly, a feminine form of the device name. The term commonly appears in technical or historical contexts rather than everyday discourse.
