Which outcome occurs when a direct bandgap semiconductor LED experiences increased temperature?

💡 Explanation

Increased temperature causes increased lattice vibrations. This influences the band structure, reducing the bandgap via electron-phonon interaction. Therefore, the peak emission wavelength redshifts because lower energy photons are emitted rather than shorter wavelengths.
