Semiconductor technology is a foundation of the information society that has been motivating human so- ciety forward by changing in production living communication and even in human. In semiconductor technology semiconductor materials play a cru- cial role. The first transistor was invented in 1947 based on germanium Ge semiconductor with a band gap at room temperature of eV. The first integrated circuit was born in 1958 and the bulk integrated circuit appeared in 1961 using germanium and silicon Si with a band gap of eV. Since 1965 silicon has become the main material for semiconductor integrated circuits. Today most semiconductor integrated circuit or photovoltaic in- dustries are still based on silicon. Silicon and germanium are often referred as the first generation of semi- conductors. The second generation including gallium arsenide GaAs band gap at
