Electronic Devices: special diodes - photo detector

[@shubhamrai3995]

Wonderfully explained sir.

[@techgurukula]

Thank you Shubham.

[@sethupathym676]

what is modulation period in here

[@utkarshpant5297]

Thank you sir
Kash ye video pehle Aya hota to responsivity ka question ban jata

[@gateexcellenceece3910]

Great explanation....Thanks sir ji...

[@techgurukula]

Thank you Dinesh for the comment!

[@geetanjalisharma6360]

Thanks so much for these lectures☺️🙏 Great explanation.. could you pls make video lecture for Schottky diode also.. ☺️Thanks in advance .

[@vasudhaavula4312]

sir,in diffusion process carriers move from high conc to low conc then y does electron diffuse in intrinsic region even though electron conc is low in p+ as compared i .could you please clarify this

[@geetanjalisharma6360]

As per my understanding, the electrons are generated due to light on top of the p region as seen in the picture, so as the conc is different on top and bottom of p region, they would diffuse and as soon as they come near depletion region, they are moved through the barrier due to electric field.. ☺️

In this quadrant Id=Io+IL ?

[@siriseniprashanthreddy1017]

Sir, how is no of e-h pairs generated equal to I/q

[@techgurukula]

Hi Prashanth, carriers generated per unit time = (no. of charge flowing per unit time)/charge of the carrier = I/q. The current we are taking here is IL, which is current due to incident light.
I missed mentioning per unit time. Hope that helps.

Thanks sir jii

[@siriseniprashanthreddy1017]

Sir could u please make videos of Ic technology, Fabrication w.r.t gate

[@techgurukula]

Yes Prashanth, will be making after BJT is complete.

[@siriseniprashanthreddy1017]

techgurukula Thank you :)

[@divya4752]

Thanks sir ji.....My favourite teacher

[@techgurukula]

Thank you Ravi!
