The core of solid-state physics is band theory, which categorizes the crystal world into two types: “insulators” and “conductors.” To fill the gap for semiconductor applications at room temperature, the concept of “semiconductors” was added. This knowledge is now taught in secondary schools, indicating that band theory has established its foundation.^_^. Of course, band theory … Read more

Most people in society would agree that among the major disciplines of natural sciences, mathematics and physics are the most authoritative, precise, and beautiful. The experience of authority is not easy to grasp, but as time spent in these fields increases, the understanding deepens. The authority of physics is reflected in the simplicity, effectiveness, and … Read more
