| 1 | In Situ Etching for Total Control Over Axial and Radial Nanowire Growth显示文摘We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth parameters.Thereby a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial growth.We demonstrate the method using etching by HCl during InP nanowire growth.The improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching. | Magnus T.Borgström Jesper Wallentin Johanna Trägårdh Peter Ramvall Martin Ek LReine Wallenberg Lars Samuelson Knut Deppert | 2010 | Nano Research2010，3，4： | 4 |

| 4 | A Comparative Study of the Effect of Gold Seed Particle Preparation Method on Nanowire Growth显示文摘Highly controlled particle-assisted growth of semiconductor nanowires has been performed for many years,and a number of novel nanowire-based devices have been demonstrated.Full control of the epitaxial growth is required to optimize the performance of devices,and gold seed particles are known to provide the most controlled growth.Successful nanowire growth from gold particles generated and deposited by various different methods has been reported,but no investigation has yet been performed to compare the effects of gold particle generation and deposition methods on nanowire growth.In this article we present a direct comparative study of the effect of the gold particle creation and deposition methods on nanowire growth characteristics and nanowire crystal structure,and investigate the limitations of the different generation and deposition methods used. | Maria E.Messing Karla Hillerich Jessica Bolinsson Kristian Storm Jonas Johansson Kimberly A.Dick Knut Deppert | 2010 | Nano Research2010，3，7： | 1 |

| 6 | In situ observation of synthesized nanoparticles in ultra-dilute aerosols via X-ray scattering显示文摘In-air epitaxy of nanostructures(Aerotaxy)has recently emerged as a viable route for fast,large-scale production.In this study,we use small-a ngle X-ray scatteri ng to perform direct in-flight characterizati ons of the first step of this process,i.e.,the en gineered formatio n of Au and Pt aerosol nan oparticles by spark gen erati on in a flow of N2 gas.This represe nts a particular challe nge for characterizati on because the particle density can be extremely low in con trolled production.The particles produced are exami ned duri ng producti on at operatio nal pressures close to atmospheric conditions and exhibit a log no rmal size distributi on ranging from 5-100nm.The Au and Pt particle productio n and detection are compared.We observe and characterize the nanoparticles at different stages of synthesis and extract the corresponding domi nant physical properties,in cludi ng the average particle diameter and sphericity,as in flue need by particle sintering and the prese nee of aggregates.We observe highly sorted and sin tered spherical Au nano particles at ultra-dilute concen tratio ns(<5×10^5 particles/cm^3)corresponding to a volume fraction below 3×10^-10,which is orders of magnitude below that of previously measured aerosols.We independently confirm an average particle radius of 25 nm via Guinier and Kratky plot analysis.Our study indicates that with high-intensity synchrotron beams and careful con sideratio n of backgro und removal,size and shape info rmati on can be obtai ned for extremely low particle concentrations with industrially relevant narrow size distributions. | Sarah R.McKibbin Sofie Yngman Olivier Balmes Bengt O.Meuller Simon Tagerud Maria E.Messing Giuseppe Portale Michael Sztucki Knut Deppert Lars Samuelson Martin H.Magnusson Edvin Lundgren Anders Mikkelsen | 2019 | Nano Research2019，12，1： | 0 |
