Figure 14From: Ge/Si(001) heterostructures with dense arrays of Ge quantum dots: morphology, defects, photo-emf spectra and terahertz conductivityTemperature dependences of the silicon substrate parameters obtained by fitting the transmission coefficient spectra as shown in Figure 13 and described in the text. (a) plasma frequency of charge carriers and (b) scattering rate. Solid line in (b) shows the T−3/2 behavior.Back to article page
