Show that in a parabolic potential well, the spacing between the energy levelsis constant. In semiconductors, parabolic potential wells are often produced byusing narrow square potential wells where the well to barrier width ratio graduallychanges. Use the virtual crystal approximation to design a GaAs/AlAs parabolicwell where the level spacing for the electron is approximately 8meV. (Hint: This isthe harmonic oscillatorproblem

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
