Question

Problem 2. a. Explain qualitatively why ni increases with increasing temperature. b. How do the properties of wide-bandgap semiconductors differ from those of narrow bandgap semiconductors? Why do you think SiC, a wide-bandgap semiconductor, is used in high-temperature semiconductor devices? The figure below may be helpful for your response. e 1013 107 4H-SiC 1011 1.0 1.5 2.0 2.5 3.0 3.5 4.0 1000/Temperature (1/K)
