Answer 1

Answer: Semi-conductors have insulator and conductor properties.

Explanation: They tend to be insulators in nature, but through a process called doping, these materials can be transformed into weak conductors. Doping is a chemical process that involves adding an impurity such as arsenic to a pure element like silicon. This change increases silicon’s ability to conduct electric charge.

Answer 2

Semi-conductors can best be described as materials that are neither normal conductors (substances that conducts electricity such as copper) or normal insulators (substances that does not conduct electricity such as rubber), but have some of the properties of both. Semiconductors that do not contain impurities do not conduct electricity but the addition of some elements to them allows easy passage of electricity through them. Examples of semi-conductors are silicon, germanium, and selenium.
