Question

Why does thermionic emission not take place in non-conductors?

Solution

For thermionic emission, material should have low work function and large number of free electrons. But nonconductor does not have free electrons and they have higher work function. So, thermionic emission does not takes place in non-conductors.

  Is there an error in this question or solution?
