# 1.18    Non-stoichiometric cuprous oxide, $Cu_{2}O$ can be prepared in a laboratory. In this oxide, copper to oxygen ratio is slightly less than 2:1. Can you account for the fact that this substance is a p-type semiconductor?

In the given compound Cu2O, the charge on Cu is +1. But the charge on copper in normal compounds is +2.

So Cu+2 will try to replace Cu+1 in atmospheric conditions.

This will lead to a generation of positive charge holes which are the cause of conductivity in p-type semiconductors.

So given compound can act as p-type semiconductors.
