Sometimes avalanche photodiodes ( APD ), photoconductivity, photoelectromagnetic, or photodiffusion devices are used even without cooling.
12.
They showed that the dark current and photoconductivity of hydrogenated amorphous silicon can be reduced significantly by prolonged illumination with intense light.
13.
In the early 20th century, Pochettino and Volmer studied the first organic compound, anthracene, in which photoconductivity was observed.
14.
Photoconductivity is the property of a material that describes the capability of incident light of adequate wavelength to produce electric charge carriers.
15.
SrTiO 3 has been shown to possess persistent photoconductivity where exposing the crystal to light will increase its electrical conductivity by over 2 orders of magnitude.
16.
He wrote a book " Concepts in photoconductivity and allied problems ", which was published by John Wiley & Sons, New York in 1963.
17.
These are photoconductivity, first observed in selenium by Willoughby Smith in 1873, and the Pockels Effect, named after Friedrich Carl Alwin Pockels who studied it in 1893.
18.
Willoughby Smith discovered the photoconductivity of the element selenium in 1873, laying the groundwork for the selenium cell phototube which was used as a pickup in most mechanical scan systems.
19.
This is called the Staebler-Wronski effect ( SWE ) a typical loss in electrical output due to changes in photoconductivity and dark conductivity caused by prolonged exposure to sunlight.
20.
After World War II, back in Kyiv, Lashkaryov investigated bipolar diffusion of photo-carriers in cuprous oxide, photoconductivity of CdS and CdSe, and also on Ge diodes and transistors.
