Abstract
The tunneling conductance was measured for a natural-barrier planar tunneli ng junction of underdoped and overdoped Bi2Sr2CaCU2O8. The temperature depe ndence of the separation between the gap edge peaks suggests that the ampli tude of superconducting gap becomes zero at the superconducting critical te mperature.
