(Solved): can you explain the answer step by step Figure I: Energy-wavenumber \( ( \) E-k \( ) \) diagram used ...

Figure I: Energy-wavenumber \( ( \) E-k \( ) \) diagram used in Question 1. The \( E-k \) diagram of a solid-state material is shown in Figure 1 (see page 3). The Fermi energy level of the material is \( E_{f}=0.6 \mathrm{eV} \). Complete this diagram by - adding the Fermi level to it; - identifying the conduction band(s), valence band(s) and bandgap(s); - shading the energy levels that electrons will occupy at \( T=0 \). Identify the type of the material (conductor, semiconductor or dielectric) and comment on the conduction properties of this material at \( 0 \mathrm{~K} \) and at \( 300 \mathrm{~K} \). Attach the completed diagram to your answer book.
