Steering self-organisation through confinement

Posted by dbos Delft

Kavli Affiliate: Gijsje H. Koenderink | First 5 Authors: Nuno A. M. Araújo, Liesbeth M. C. Janssen, Thomas Barois, Guido Boffetta, Itai Cohen | Summary: Self-organisation is the spontaneous emergence of spatio-temporal structures and patterns from the interaction of smaller individual units. Examples are found across many scales in very different systems and scientific disciplines, […]

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 […]
