WebJul 2, 2024 · What is an energy band diagram? In solid-state physics of semiconductors, a band diagram is a diagram plotting various key electron energy levels (Fermi level and nearby energy band edges) as a function of some spatial dimension, which is often denoted x. A band diagram should not be confused with a band structure plot. WebSep 7, 2024 · Band diagrams As we saw for hydrogen in lecture, band diagrams can be thought of as the continuum limit of MO theory, allowing us to think about a long chain of bonds (or even a crystalline solid!) instead of just a dimer. To recap, let's imagine what building up a carbon solid - diamond- would be like. tebal uang 100 ribu
