摘要：

The evolution of local electronic states in NiS2-xSex pyrite as a bandwidth-controlled metal-insulator transition (MIT) approached from the metallic side is explored by scanning tunneling microscopy/spectroscopy (STM/STS). Atomically resolved images of Se/S zigzag chains are observed on top of the cubic (100) surface, and a narrowing of the quasiparticle band near the Fermi level is clearly identified in tunneling spectra. In marked contrast to MIT's control by doping, the local electronic states are found to be spatially homogeneous even in the vicinity of the MIT.
