Abstract: IR photodetectors have been made on Pb/δ-layer/p-Pb1 –xSnxTe1 –ySey/p+-Pb0.8Sn0.2Te/Au and Au/δ-layer/n-Pb1 –xSnxTe1 –ySey(BaF2)/Pb surface-barrier structures prepared by liquid-phase epitaxy and thermal evaporation. At ~170 K, peak wavelength λp ~ 7.9–8.2 μm, and cutoff wavelength λc… read more here.
