With the increase in temperature, the concentration of charge carriers (electrons and holes) increases. As more charge carriers are made available, the conductivity of a pure semiconductor increases i.e. resistivity of a pure semiconductor decreases with the rise in temperature. Therefore semiconductors have negative temperature coefficient.

Electronics basics Q&A
Ma'am upload more videos on electronic devices
Yes. I will do..

mam why temp. coefficient is -ve for semiconductor
With the increase in temperature, the concentration of charge carriers (electrons and holes) increases. As more charge carriers are made available, the conductivity of a pure semiconductor increases i.e. resistivity of a pure semiconductor decreases with the rise in temperature. Therefore semiconductors have negative temperature coefficient.
Thank you mam
Mam advance semiconductor device pada do
Could u provide the notes mam?
Ma'am this is full course?
Mam what's course code of this subject
It's KEC-301
But content is same for many universities...
Mam isa ka pdf download kase hoga
Notes kaise milenge mam
Mam pdf de Diya kro n
