Is SiO2 a good semiconductor material?
The moderately doped semiconductor is more likely to reflect the semiconductor properties, i.e., the resistance decreases as the temperature increases, and the conductivity increases (as opposed to the metal conductor, the metal increases with temperature, and the resistance increases). Silicon is therefore good because it has a wide range of operating temperatures.
Pure silicon is a good semiconductor material. But the application of silicon must have the purpose of limiting the incorporation of a particular element, known as doping.
Silicon dioxide is not a semiconductor, but an insulator.
