hey can anyone help me about this :
what is the influence of heat and light on the conductivity of semiconductors?
thanks

heat and light affect the conductivity of semiconductors by increasing it.

As energy is applied to the electrons of the atoms in a semiconducting material they are able to jump from the valency band acroos the forbidden gap and into the conduction band.

thanks mate
can i get more details about that?

Um that pretty much covers it man... Your looking for a definition or an explanation?

 

[zzyookcuc]

um i think explanation it's better
also there is another way to understand like :
explanation of the effect of heat on semiconductors and
explanation of the effect of light on semiconductors
!!!!!!!!!!

 

[:: ck ::]

both heat and energy provide electrons with kinetic energy to jump from the valence to the conduction band thus impproving it's conducting properties
