GaInAsSb/GaSb/GaAlAsSb double heterostructures are attractive for optoelectronic devices working in the 1.5-4.8,mu m wavelength region. In this paper, the current mechanisms of liquid phase epitaxy grown GaInAsSb based double heterostructures with 100,mu m diameter were investigated in the temperature range 77-350 K. It was found that diffusion current dominates at the high temperature (> 240 K) and small forward bias region, while generation-recombination current dominates at intermediate temperatures (242-171 K). At low temperature region (< 171 K), the tunneling mechanism of the current flow dominates in both forward and reverse biases.
