Refractive index for sample 847, obtained from the fit, is slightly higher than that estimated by PUMA software, because this film contains a small amount of silicon (see Table 2). The theoretical refractive index for an a-Ge:H film would be 4.5 at 1310 nm, and 4.38 at 1550 nm, as can be seen in Fig. 8.

The relative permittivity of SiC exhibits a sharp resonance near 800 cm 1 (12:5 m) due to excitation of transverse optical phonons [6] [Fig. 1(a)]. At the high frequency side of this resonance,

Niobium - Wikipedia

2019-4-2 · Niobium, formerly known as coluium, is a chemical element with syol Nb (formerly Cb) and atomic nuer 41. It is a soft, grey, crystalline, ductile transition metal, often found in the minerals pyrochlore and coluite, hence the former name "coluium".Its name comes from Greek mythology, specifically Niobe, who was the daughter of Tantalus, the namesake of tantalum.

Those are extraordinarly wide ranges for a single gemstone variety. The reason for the large variation in basic gemological properties is that some Zircon specimens are transformed by natural radiation.
