Silicon Carbide – A Mirror Material For Astronomical Telescopes
Silicon carbide is an outstanding semiconductor material with a wide band-gap and high electron mobility, as well as low thermal expansion and hardness properties – ideal features for mirror materials in astronomical telescopes. Figure 5(a) displays Fresnel normalized XRR patterns of SiC/Si films of different thicknesses with Fresnel normalization applied. Circles represent experimental data while …
