sávhatárok
Sávhatárok, or band edges, is a term used in physics and engineering to describe the boundary energies or frequencies that delimit a band. The concept appears in several contexts, most prominently in solid‑state physics and in the management of electromagnetic spectra.
In solid‑state physics, electrons in a crystalline solid occupy continuous energy bands separated by gaps. The
In communications and signal processing, a band refers to a continuous range of frequencies, and the band
Techniques to determine band edges include photoemission spectroscopy (ARPES), optical absorption and photoluminescence measurements, ellipsometry, and
