Abstrakt: Proposes a semiempirical model that correlates the broadening of the absorption edge with both transitions below the energy gap and with transitions by the Kane band model. Information on (Hg,Cd)Te; Mechanisms that contribute to the broadening of the absorption edge; Potential causes of the permanent broadening of the absorption edge; Difference between the Urbach tail and the square-root region.
