1) The energy gap of Si at 300 K is 1.11 eV. Assume that n = 10^16 /cm^3 . We know that for an undoped/intrinsic Si sample that ni = 1.5x10^10/cm3 . Thus this is a doped n-type Silicon sample. 1a) Obtain the hole density p at 300 K for this sample. 1b) Obtain EF – Ei, in eV 1c) Obtain EC – EF, in eV 1d) Sketch the bands (don’t worry about the horizontal axis, just the position of...

Calculate P versus molar volume behavior of water at three different temperatures: 300 K, 400 K...

Calculate P versus molar volume behavior of water at three different temperatures: 300 K, 400 K and 500 K using vander Waals equation of state. Your results should show both extrema. Using the diagrams you generated in part 1, determine the equilibrium pressure: the pressure at which the areas above and below the isobar are identical. Compare your results with the data reported in the steam tables.
