Question

silicon and germanium which has more free charge carrier density at room temperature why

Answer 1

Answer:

Germanium

Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than germanium.

Answer 2

answer

because they have more number of OH3 + ions

Explanation:

so the silicon germanium which have more density ..
