Original Abstract

Temperature dependence of the Hooge parameter of the p- and n-type InGaAs heterostructures was measured in the 14K -- 300K region and compared with the mobility to find correlation between the 1/f noise characteristics and scattering processes in the semiconductors. The n-type sample's Hooge parameter is nearly 2x10-3 at 300K and p-type's about unity and these values change about one order down to 14K mainly due to the influence of traps. Experimental results were analysed in terms of the cross correlation quantum 1/f noise and the 1/f energy partition fluctuation thoery and good argument was found for the latter model.
