Negative Differential Resistance Induced by Mn Substitution at SrRuO3/Nb:SrTiO3 Schottky Interfaces

Y. Hikita, L. Fitting Kourkoutis, T. Susaki +3

We observed a strong modulation in the current-voltage characteristics of SrRuO${}_3$/Nb:SrTiO${}_3$ Schottky junctions by Mn substitution in SrRuO${}_3$, which induces a metal-insulator…
