Experimental band structure E( k r) of V₃Si by angle-resolved photoemission

Band dispersions E(k) and critical points of V3Si have been determined by k-selective angle-resolved photoemission with synchrotron radiation. A V-3d band (Δ1,2) which is very close to EF at Γ (Γ12) has been observed which is very flat near Γ along the ΓX direction, in agreement with recent APW calculations. Critical points of valence bands as well as their orbital character and density of states features have been determined. © 1981.
