Question

why Silicon and Germanium are used in making semiconductors?????
hiii guys ans. this​

Answer 1

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're metalloids

Explanation:

Silicon and germanium are used here effectively because they have 4 valence electrons in their outermost shell which gives them the ability to gain or lose electrons equally at the same time . Silicon material has been widely used in semiconductor device fabrication because of its low cost and its productivity of high quality silicon dioxide needed for impurity diffusion and surface passivation processes.
