Low-Frequency Noise Characteristics of InGaAs/InAlAs Heterostructures

Original language description

The low frequency noise of InGaAs/InAlAs heterostructures with various In concentration was measured in wide temperature range of 15K up to 450K and experimental characteristics compared with theoretical models of mobility fluctuations due to various scattering processes. Several p- and n-type doped lattice-matched In0.53Ga0.47As/In0.52Al0.48As samples prepared by NTT reveal Hooge parameter alpha(H) congruent to 1 and alpha(H) congruent to 2 x 10(-3), respectively, which is consistent with the 1/f energy partition fluctuations model. However, most of the n-type samples give alpha(H) values of 4x10(-6) to 3x10(-5) or slightly higher in case of In0.7Ga0.3As/In0.52Al0.48As pseudomorphic structures, which is closer to the quantum 1/f noise theory prediction of Hooge parameter about alpha(H) congruent to 10(-6). Using the TLM structures noise analysis we determined, that contact noise was almost negligible.
