摘要: Abstract We addressed the inconsistency between electron mass anisotropy ratios determined by far-infrared experiments and DC conductivity measurements. By eliminating possible sources of error increasing sensitivity resolution in reflectivity measurement on single crystalline polycrystalline La1.84Sr0.16CuO4, we have unambiguously identified that source problem is estimation free density involved charge transport. In this study found only 2.8% total doping-induced itinerant at optimal doping. Our result not resolves puzzle but also points to a novel electronic structure formed rest electrons.
