Non-stoichiometric cuprous oxide, Cu2O can be prepared in laboratory. In this oxide, copper to oxygen ratio is slightly less than 2 : 1. This substance is a?
Options:
Answer:
A
Solution:
The ratio of copper to oxygen is slightly less than 2 : 1. This shows that some cuprous (Cu+) ions have been replaced by cupric (Cu2+) ions. In order to maintain the electrical neutrality of the molecule, every two Cu+ions will be replaced by one Cu2+ion which results in creating cation vacancies leading to positive holes. Since the conduction is due to positive holes, it is a p-type semiconductor.
