Schottky Contacts to ZnO-Nanocoated SnSe Powders by Atomic Layer Deposition.

In this study, SnSe powders are nanocoated with ZnO grown by atomic layer deposition (ALD) with different ALD ZnO pulse cycles. Subsequently, the current transport mechanisms of Pt/ZnO-coated SnSe junctions are electrically investigated. A decrease in the current and an increase in the series resistance are observed at 300 K with increasing ZnO pulse cycles (, increasing the thickness of the ZnO layer).
