Silicon and Germanium

Silicon and Germanium:

                                 fig the atomic structure of Silicon and Germanium are given we compared the atomic structures of Silicon and Germanium to each other. Silicon is used in semiconductor devices, diodes and integrated circuits. Both have four valence electrons. It is often say that silicon have valence electron in the 3^rd shell and in the germanium the four valence electrons are in 4^th shell. This shows that the silicon has less energy level and germanium has high energy level an extra additional energy is required to escape from the atom. At high temperature it makes the germanium more and more stable. That’s way the silicon is mostly used semiconductor.
