Abstract
The preliminary results of the surface characterization of Nd1Ba2Cu3Oy (Nd123) single crystals employing ultrahigh vacuum scanning tunneling microscopy/spectroscopy (UHV-STM/STS) at room temperature are reporte d. The natural surface termination layer is unambiguously determined. STS measurements show that the as-prepared surfaces of Nd123 single cr ystals are semiconductive and are clean and stable in air. Our results suggest that Nd123 single crystals are good candidates for surface-se nsitive scientific research.
