摘要：

We report the synthesis and characterization of a unique US architecture made of two intersecting ribbons that form a ridge-shaped bicrystalline US nanoribbon via simple thermal evaporation of US powder. The US bicrystalline nanoribbons have a tapering width decreasing from 600 to 50 nm and lengths of several tens of micrometers. The nanostructures show strong band gap emission and weak defect-related emission. Zigzag US bicrystalline nanoribbons are occasionally formed at the tip region,
