WebApr 1, 2024 · These electrons are more probable to occupy the valence bond energy than the conduction band. This creates a level called the Fermi level which is close to the valence bond. So, the correct answer is “Option C”. Note: Semiconductors are materials which are made up of holes and electrons. Web2 days ago · The calculated value of formation energy is −0.839 R y. This negative value of formation energy confirms the structural stability of Co 2 TiGe compound. The strain is applied on Co 2 TiGe from −6% to +8%. It is observed that when tensile strain from 0 to 8% is applied on Co 2 TiGe, the energy band gap decreases as the strain is increased. atelie barbara
