CORE AND VALENCE LEVEL PHOTOEMISSION-STUDY OF THE COMPOSITION DEPENDENT METAL TO NONMETAL TRANSITION IN THIN-FILM BI2.1SR1.7CA0.85-XYXCU2O8+DELTA
The composition dependent metal to non-metal transition in a series of single phase, two copper-layer, strongly c-axis oriented thin films of composition Bi2.1Sr1.7Ca0.85 - xYxCu2O8+δ has been studied using core and valence level photoemission. The decrease in itinerant hole concentration brought ab...
