As seen from these spectra, their intensities increase almost linearly with increasing boron concentration from 5 × 1017 cm−3 up to 4 × 1018 cm−3 and do not practically change from 4 × 1018 cm−3 up to 2 × 1020 cm−3 (Fig. 5).
"When I came back, everything had practically changed," says Benson, now the Commissioner for Engineering for the Liberia Telecommunications Authority.
The type of adsorption sites strongly affect the conductivity for random and correlated adatoms, but practically does not change the conductivity when they form ordered superstructures with equal periods.
The calculations also show that, in contrast to the case of local defect sink, the local region of elastic stresses practically does not change the distribution of defects beyond this region if there is no generation/absorption of point defects within the strained layer.
