Abstract :
The electrical and optical properties of two p-n junction configurations (transverse and coaxial) have been investigated utilizing PbTe filamentary crystals with the diameter 10-120 μm. The detectivity values Dλmax* up to 2·1010 cm·Hz1/2W-1 have been achieved for unbiased single filamentary detectors. The pulsed laser action was observed at T=4.2 K (λ=6.5 μm). The total internal reflection modes and the isotropic radiation pattern in the p-n junction plane were observed
