Wien displacement law:
For blackbody, the product of the wavelength equivalent to the maximum radiancy and the thermodynamic temperature is a constant, the Wien displacement law constant. Consequently, as the temperature grow the maximum of the radiant energy shifts to the shorter wavelength (higher frequency and energy) end of the spectrum.
At 200.0 K, germanium has 1.16 x 10 10 thermally liberated charge carriers/cm 3 . If it is doped with 1 As atom to 525,000 Ge atoms, what is the ratio of doped carriers to the
