Abstract
We have employed photoelectron spectroscopy to follow the development of the one-electron spectral function for Ti3d electrons in Nd1-xSrxTi O3 as a function of x. For x < 0.25, only incoherent intensity associa ted with the lower Hubbard band is present. Additional intensity, attr ibuted to a coherent quasiparticle contribution, appears at the compos ition of the metal-insulator transition, x similar to 0.25. The relati ve intensities of these two components are determined as a function of x.
