The absorptivity of high-purity grades of silicon (Si) and its reduction by subsequent doping procedures are investigated.

The dielectric data are given for the wide range of frequencies (30 – 330 GHz) and temperatures (30 – 330 K) in comparison with the data set for sapphire. The advanced material performance in high power window applications is discussed taking into account both dielectric properties of the optimized silicon grades and thermal conductivity.
