a) 6.22*10^18
No idea for b) any thoughts or how to for b)?
(a) Silicon (50 g) has been doped with 27 mg of antimony (Sb). Determine the concentration of free charge carriers (carriers/cm3) at room temperature in this material.
(b) Calculate the absorption edge of this material. Express your answer as a wavenumber in units of inverse meters.

b please...
b) 10^7 / lamda*(wavelength in nm)
something wrong i cant got it
rufus, please what is answer
1.09E13
WRONG
wavenumber= Eg / hc
Eg(Silicon band energy)= 1.11 eV (to joules)
h=6.6*10^-34
c=3*10^8
wavenumber= Eg*1.6*10^-19 / hc = 896969.69
Eg(Silicon band energy)= 1.11 eV (to joules)

thanks
Thank you for the explanation.
