规则锑化铟团簇颗粒的制备

采用低能团簇柬流淀积（LECBD）装置，在不同温度的衬底上，制备得到不同形貌的锑化锢团簇颗粒，如三角形颗粒、六边形薄片和长方体颗粒等，形貌的差别认为是由锑化锢各向异性生长所致。     

Synthesis and magnetotransport properties of Bi_2Se_3 nanowires

Bi_2Se_3, as a three-dimensional topological insulator, has attracted worldwide attention for its unique surface states which are protected by time-reversal symmetry. Here we report the synthesis and characterization of high-quality singlecrystalline Bi_2Se_3 nanowires. Bi_2Se_3 nanowires were synthesized by chemical vapor deposition(CVD) method via goldcatalyzed vapor-liquid-solid(VLS) mechanism. The structure and morphology were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), x-ray photoelectron spectroscopy(XPS), and Raman spectroscopy. In magnetotransport measurements, the Aharonov–Bohm(AB) effect was observed in a nanowire-based nanodevice, suggesting the existence of surface states in Bi_2Se_3 nanowires.
