Paper Abstract

InAs and InAs(Sb)(P) based heterostructures with InAsSbP claddings grown onto heavily doped or undoped n-InAs substrates have been processed into 230÷430 &mgr;m wide mesa flip-chip devices operating in the 3÷5 &mgr;m spectral range. We present temperature dependence of I-V, RoA, SI and D* as well as the dependence on a photon energy in uncoated backside illuminated and equipped with an immersion lens photodiodes respectively. Room temperature D*&lgr; as high as (1.75x1011÷3x108) cmHz1/2W-1 was achieved in photodiodes with Si lens having effective diameter of 3.3 mm and operating in the 3÷5 &mgr;m range correspondingly.
