Three key features are found. Firstly, within 0.2 mV there is a dome like conductance enhancement due to Andreev reflection at the normal-superconducting interface. By pushing the W tip further, the conductance enhancement increases from 3\\% to more than 20\\%, much larger than that was previously reported, probably due to the pressure exerted by the tip. Secondly, there are also superconducting like fea","authors_text":"He Wang, J.E. Ortmann, Jian Wei, Jiawei Luo, Weijian Lou, Y. Liu, Z.Q.
