Chapter 16, Problem 39R

To determine

To explain: The reason that germanium and silicon are not efficient conductors.

Explanation of Solution

Introduction:

A tabular display of the chemical elements is known as a periodic table. In a periodic table, the elements are arranged by their atomic numbers, chemical properties and electronic configuration.

According to the periodic table, the elements germanium and silicon are located on the staircase. The elements located there have the properties of metals as well as non-metals. So, they are not efficient conductors.

Conclusion:

Hence, germanium and silicon are used in making semiconductors.
