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

arus gelap


Definition from Dewan Bahasa dan Pustaka - Pusat Rujukan:
Arus elektrod yang mengalir apabila tiada fluks sinaran tuju pada fotokatod dalam fototiub atau tiub kamera.

Example sentence(s):
  • Arus gelap terbentuk akibat penjanaan cas elektrik secara terma dan penjanaannya berkadar secara linear dangan masa. - Agensi Angkasa Negara Malaysia  
  • Ringkasan ciri-ciri arus gelap dan arus foto, faktor idealiti dan ketinggian sawar bagi sampel yang dirawat dengan rawatan pembersihan. - USM Malaysia  
  • Isyarat yang terhasil mestilah berkadar terus dengan kuasa pancaran, P iaitu G = KP +k’ Dimana G = rangsangan elektrik pengesan dalam unit arus, rintangan atau emf K = pemalar kadaran, kepekaan pengesan dalam bentuk sahutan elektrik per unit kuasa sinaran k’ = arus gelap, iaitu sahutan atau rangsangan elektrik yang ditunjukkan walaupun tidak ada kuasa sinaran yang kena. - UKM: SPEKTROSKOPI
