Abstract

We present experimental evidence for the instability of photogenerated charge carriers (photocarriers) against phase separation into metallic domains in the CuO2 planes. Our results of photoinduced infrared absorption measurements on La2CuO4 indicate that photocarriers are inhomogeneously distributed in the CuO2 planes, forming metallic domains which condense into the superconducting state at low temperatures with an onset at T ≈ 40K.
