By examining the nonlocal conductance, we identify the closure of the excitation gap in the bulk of the semiconductor before the emergence of zero-bias peaks, ruling out spurious gap-closure signatures from localized states. We observe that after the gap closes, nonlocal signals and zero-bias peaks fluctuate strongly at both ends, inconsistent with a simple picture of clean topological superconductivity."}],"isi":1,"oa_version":"Preprint","type":"journal_article","article_processing_charge":"No","department":[{"_id":"AnHi"}],"issue":"23","volume":103,"quality_controlled":"1","publication_status":"published","status":"public","_id":"9570","author":[{"first_name":"Denise","last_name":"Puglia","id":"4D495994-AE37-11E9-AC72-31CAE5697425","full_name":"Puglia, Denise"},{"full_name":"Martinez, E.
