Preview Abstract
We present point contact tunneling spectroscopy measured on TlBa₂Ca₂Cu₃O_10-δ (Tl1223) with three CuO₂ planes in a unit cell. Our samples of Tl1223 with T_c~91K are heavily overdoped at the outer CuO₂ planes (OP), but slightly underdoped at the inner CuO₂ planes (IP). The tunneling conductances on Tl1223 exhibit two kinds of gaps that originate from crystallographically inequivalent IP and OP. The overall spectral shape of tunneling conductance for Tl1223 is consistent with that observed on a bilayer Bi₂Sr₂CaCu₂O_8+δ, that is, unusual peak-dip-hump (PDH) structures are observed. The origin of PDH structures is controversial, but these results, especially, the observation of PDH for trilayer Tl1223 in which interlayer effects should be quite different from that in bilayer, put severe constraints on any theoretical model for the origin of these structures.
