L. Rodríguez-Hahn,B. Esquivel,J. Cárdenasdepends on the electronic band structure of the material. For example, it depends on whether the lowest band-to-band transition is direct or indirect (in many-valley structure) in the wave-vector space and whether the direct transition is dipole-allowed or -forbidden and the indirect one is phonon-allowed or -forbidden.

NGN Standardization as a Strength standards bodies and highlights their main "products", such as the Next Generation Network on the fixed side for ETSI TISPAN or 3GPP Release 5 and later for the mobile side. Some explanations are also given on how these bodies work together - or sometimes against each other.
