Abstract

Kondo insulator is one of the systems which got particular interest, but
not yet understood well. Metal-insulator (MI) transition by doping in
these systems is one of the examples poorly understood. U3M3Bi4 forms in
the same crystal structure with Ce3Pt3Bi4, which is well known Kondo
insulator. We have succeeded in synthesizing new single crystals of
U3M3Bi4, where M = Rh, Ni, with metallic Kondo lattice and
semiconducting behaviors, respectively. It provides the opportunity to
investigate metal-insulator transition in Kondo insulating system without
affecting the crystal structure.
