2020/7/22· Chapter 2 reviews the state of the art of wide band- gap materials. The fundamental limit to high-tempera- ture operation is the energy of the semiconducting bandgap of the host material. By this measure, even silicon with its "small" bandgap (1.1 eV) is not wide- ly used near its limit of 300 °C (silicon as a high- temperature material is discussed in Appendix A).
