Unformatted text preview: homoepitaxy will be successful or not under these conditions. Q5: Step‐mediated homoepitaxial MBE growth is performed on a Si substrate, which has a miscut angle of 0.1o. Estimate the minimum temperature required for step‐mediated growth at a rate of 5 ML/sec. Q6: Compare and contrast these three diffraction methods, RHEED, LEED and TEM. Your discussion should include the different accelerating voltages used in the there different techniques, the effect of the accelerating voltage on the radius of the Ewald sphere, the nature of the diffracting species (reciprocal lattice points, reciprocal lattice rods, or reciprocal lattice planes), and the relative size of the Ewald sphere to the diffracting species....
