Comparision between (111)B and (100) III-V nanowhiskers
Författare
Summary, in English
Epitaxial III-V nanowhiskers have been grown with orientation in the [111]B and [100] directions. While the nature of the crystal structure in the (111)B type of whiskers varies more or less at random between hexagonal (wurtzite) and cubic (zincblende) structure, the (100) type whiskers are of single crystal zincblende structure. We show that the bounding surface facets of the whiskers are either {110} type (zincblende) or the related {1120} facets (wurtzite), giving a rectangular cross-section of (100) whiskers and a hexagonal cross section of (111)B whiskers. The variations in crystal structure and facet type are discussed in connection to the electronic properties of the whiskers and the choice of whisker type for applications in electronics and photonics
