Question 193: Semiconductors and Logic Gates

Question

A solid which is not transparent to visible light and whose conductivity increases with temperature is formed by

Accepted Answer

Van der Waal's bonding is attributed to the attractive forces between molecules of a liquid. The conductivity of semiconductors (covalent bonding) and insulators (ionic bonding) increases with increase in temperature while that of metals (metallic bonding) decreases.
