combined with transparent ZnO thin films The anti-reflective effect, and thus greatly enhance the efficiency of silicon light emitting diodes.
The components of the room Wen Faguang spectrum peak at the wavelength of 1140 nm, very close to the silicon energy band gap, corresponding to the phonon assisted carrier with non-direct (phonon-assisted indirect carrier recombination) the physical mechanism. The researchers also measured the DC current into the light of different power. This component a
