Abstract (English)

The mechanism for the superconductor-insulator transition in disordered films, the transition from a weak superconductor into a strong insulator at low temperature, is still an open question. One key issue is whether superconductivity is the driving force of this insulating behavior and to which extent charging effects play a role. In this work high resolution dc current-voltage characteristics ...


Translation of the abstract (German)

Der Supraleiter-Isolator Übergang in dünnen Filmen ist der Übergang von einem schwachen Supraleiter in einen starken Isolator. Eine zentrale Frage ist, in wie weit Supraleitung an der Bildung des isolierenden Zustands beteiligt ist. Hochaufgelöste Strom-Spannungs Kennlinien wurden im Rahmen dieser Arbeit untersucht. Es ergeben sich Nicht-Linearitäten bei hohen wie auch bei kleinen Vorspannungen. ...
