What Is The Electrical Conductivity Of Magnesium Sulphide?

Magnesium sulphide (MgS) is an ionic compound consisting of magnesium cations (Mg2+) and sulphide anions (S2-). As a result of this ionic character, MgS is an insulator at standard conditions.

However, under certain circumstances, MgS can exhibit some degree of electrical conductivity. For example, when MgS is doped with impurities such as nitrogen or oxygen, it can become a p-type semiconductor, meaning that it has an excess of positively charged holes that are able to conduct electricity. The exact value of electrical conductivity for doped MgS would depend on the specific conditions and doping concentration.

It's important to note that pure MgS is not considered a good conductor of electricity, and is typically used as an insulating material in electronic applications.
