English term or phrase: dark current

Definition from Tyco Electronics Corporation:
The thermally induced current that exists in a photodiode in the absence of incident optical power.

Example sentence(s):

This voltage may be as low as 10 mV or as high as 50 V and the dark currents may vary from pA to μA depending upon the junction area and the process used. Dark current is always specified at a particular value of reverse applied voltage. optoelectronics.perkinelmer.com
The photodiode noise in is the sum of the thermal noise (or Johnson noise) ij of a resistor which approximates the shunt resistance and the shot noise isD and isL resulting from the dark current and the photocurrent. Hamamatsu Corporation
Dark current is dependent on temperature. While dark current may initially be low, it will increase as the device temperature increases. tpub.com

mørkestrøm

Definition from own experience or research:
Strømmen som ledes gjennom dioden når den er i av-tilstand - altså når infallende lys ikke er tilstrekkelig til å åpne dioden.

Example sentence(s):

Med andre generasjons detektorer forstår vi systemer med stirrende fokalplan arrayer (FPA) bestående av fotovoltaiske todimensjonale array. Det vil si fotodiodebasert teknologi som produseres i tusentall årlig. Fordelen med denne teknologien er høy impedans som gir lav mørkestrøm(nA) og enkel utlesningselektronikk. - Sensorteknologi for fremtidig UAV

Explanation:
Tilsvarend bruk på svensk (mörkerström) og dansk (mørkestrøm).
