| Abstract: | Absorption spectra near the fundamental absoption edge of n‐type of In1‐xGaxAs are studied. The temperature coefficient of the In1‐xGaxAs energy gap, dEg/dT, has been obtained and compared with calculated data. An exponential dependence of the absorption coefficient on photon energy has been found. The slope of the exponential absorption curve is discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co.
