Tunneling spectroscopy of Tl2Ba2CuO6
New results from tunneling spectroscopies on near optimally doped single crystals of Tl2Ba2CuO6 (Tl-2201) junctions are presented. The superconductor-insulator-normal metal (SIN) tunnel junctions are obtained using the ...
Tunneling spectroscopy of heavily underdoped crystals of Bi2Sr2CaCu2O8-δ
Crystals of Bi2Sr2CaCu2O8+δ with optimal Tc=95 K have been underdoped using two different methods and the superconducting gaps have been obtained by tunneling. In some cases, three different tunneling geometries have been ...
