thank you sir
sir what is the use of dark current.. in reverse bias the current generated due to light is in micro amperes where do we use this current in real time application?
Optical communication by using this photo diode in reverse bias
@@EngineeringFunda thank you sir
Please explain,Why Covalent bonds are stronger in p/n type than compared to depletion region?
Thanks in advance
In Depletion region, there will be ions only and with ions covalent bonds are always weaker compared to normal Semiconductor material. You can study that from energy band diagram even.
Thanks for reply. Please provide reference for this.
Konda ji Etna Kam h kya
idk
I think it is not necessarily accurate to say that covalent bonds in the p/n-type regions are stronger than those in the depletion region. The correct perspective is that in the p/n-type regions, electron-hole pairs, or excitons, rapidly recombine because there's no electric field to separate them, thus they do not contribute significantly to the photocurrent.
sir! can you make a video on PHOTO TRANSISTOR?
yes
Sir Hindi medium me bachhe jayada hai plz Hindi medium
