Metal-insulator Crossover Behavior at the Surface of NiS_2
D. D. Sarma, S. R. Krishnakumar, E. Weschke +8
We have performed a detailed high-resolution electron spectroscopic investigation of NiS and related Se-substituted compounds NiSSe, which are known to be gapped in…

Electronic structure of NiS_{1-x}Se_x
S. R. Krishnakumar, N. Shanthi, Priya Mahadevan +1
We investigate the electronic structure of the metallic NiSSe system using various electron spectroscopic techniques. The band structure results do not describe the det…

Electronic structure of NiSSe across the phase transition
D. D. Sarma, S. R. Krishnakumar, Nirmala Chandrasekharan +4
We report very highly resolved photoemission spectra of NiS(1-x)Se(x) across the so-called metal-insulator transition as a function of temperature as well as composition. The prese…
