Normalization procedure for obtaining the local density of states from high-bias scanning tunneling spectroscopy

Posted by dbos Delft

Kavli Affiliate: Sander Otte | First 5 Authors: Rasa Rejali, Laëtitia Farinacci, Sander Otte, , | Summary: Differential conductance spectroscopy performed in the high bias regime — in which the applied voltage exceeds the sample work function — is a poor measure of the local density of states due to the effects of the changing […]
