Summary: The growth process of Ge crystals catalyzed by Au was investigated through molecular dynamics simulations, establishing relationships between the overall Ge growth rate and synthesis conditions. The dynamic behaviors of Ge atoms near the liquid-solid interface were captured, and the interface properties were linked to the surface morphologies to explain the observed orientation-dependent growing modes.

Summary: This study investigates the consumption of apical gallium droplets in the growth of GaP nanowires, revealing four channels of liquid gallium consumption. By conducting complementary experiments and detailed calculations, the dynamics of the system exposed to a constant external phosphorous flux are numerically computed. The quantitative model developed in this study can predict the changes in droplet contact angle and radius, which are crucial for controlling the crystal phase of III-V nanowires and fabricating quantum size structures.

Summary: This paper reports on the growth of in-plane silicon nanowires (SiNWs) catalyzed by Sn and their application in nano-electronics. The solid-liquid-solid (SLS) mechanism allows for high tin concentrations in the SiNWs, exceeding the expected concentration by over 1000 times. Atom probe tomography and transmission electron microscopy were used to analyze the composition of the SiSn NWs, revealing similar distribution of Sn atoms in crystalline SiSn NWs grown at different temperatures, with different sn-enrichments along structural defects. A NW-based field-effect transistor (FET) was fabricated using a SiSn NW as the charge transport channel, achieving a field effect hole mobility of 80 cm2/V.s.

Summary: This study theoretically investigated the role of surface energy in the growth of III-V nanowires, finding that the expansion of the monolayer may not be a continuous process, with dissolution on one side and simultaneous growth on the other. This discovery contributes to a better understanding of nanowire growth mechanisms and has potential impacts on the statistics, crystal phase, and doping properties of nanowire ensembles.

Summary: This study demonstrates the growth of silicon nanowires (Si NWs) using magnesium (Mg) as a catalyst material. The Si NWs grown with Mg show high mass loadings and tight diameter control. They exhibit high initial coulombic efficiencies and high gravimetric and areal capacities as anodes for lithium-ion batteries.

Summary: High quality silicon nanowires (SiNWs) are grown at a rapid rate on polymer/glass substrates using self-selected laser heating of indium catalyst droplets, allowing for deterministic diameter modulation in ultralong SiNWs through rapid laser ON/OFF switching. Prototype field effect transistors fabricated on these SiNWs show a high I-on/I-off ratio and reasonable subthreshold swing, providing a new route for high-performance flexible electronics on large area and lightweight polymer substrates.

Summary: The direct phase transformation of ReO3 nanorods into 2D nanosheets of ReS2 on carbon fibres (CNFs) using a reducing heat treatment and induction of a sulfurization reaction is reported. The gas sensing abilities for NO2 and H-2 were also explored by investigating the change of electrical characteristics of both 2D ReS2 nanosheets and ReO3 nanorods on CNFs.

Summary: This study reports the growth of large-composition-range pure-phase InAs1-xSbx nanowires on Si substrates by molecular beam epitaxy. The pure-phase nanowires were obtained by controlling the antimony content, nanowire diameter, and growth direction. The antimony was uniformly distributed in the nanowires and no spontaneous core-shell structures were observed. The nanowires exhibited good conductivity with high mobilities at 7K.

Summary: Selective area growth of Pb1-xSnxTe islands and nanowires is demonstrated, and their in-depth growth dynamics and faceting are analyzed. The material is confirmed to be single-crystalline and defect-free, with homogeneous Pb/Sn ratio in the nanowires. {110} directions are identified as the optimal candidate for the growth of high-quality and straight Pb1-xSnxTe nanowires, enabling the design of complex networks.

Summary: In this study, we demonstrate the growth of single-crystalline i-Si, i-Si/n-Si, and SixGe1-x/SiyGe1-y nanowires via the Geode process. The use of microcapsules improves scalability while maintaining programmability of the nanowires. Heat and mass transport limitations introduced by the microcapsule wall are shown to be negligible, allowing for consistent compositional control. The efficient transport also minimizes structural variations in nanowires grown in microcapsules with different sizes and wall thicknesses.

Summary: Template-assisted selective area growth techniques, such as confined epitaxial lateral overgrowth (CELO), have been utilized to grow epitaxial materials in prefabricated dielectric templates with defined nanostructure geometry. Low-temperature magneto-transport measurements were used to determine electronic properties, showing Shubnikov-De Haas oscillations in the longitudinal magnetoresistance in doped In0.53Ga0.47As CELO nanostructures. Analysis of these oscillations revealed defects and material variabilities, while electron beam lithography and contact deposition allowed for transport measurements. This approach has the potential to explore confined lateral epitaxy in other material systems, improve material quality, and investigate quantum transport phenomena in nanoscale devices.

Summary: Introducing local volume extensions to silicon nanowires can effectively control the growth rate of metal silicides, decouple the growth process from variations in metal supply, suppress Ni-rich silicide phases, and promote the formation of single-crystalline Ni-Si phases. This method helps reduce silicidation in nanowires and improve device performance.

Summary: This study presents the fabrication of highly uniform indium catalyst droplets using a nanostripe-confined approach, which enables the uniform growth of an orderly array of silicon nanowires (SiNWs) via in-plane solid-liquid-solid (IPSLS) growth directed by step edges. The improved droplet uniformity translates into a more uniform growth of ultrathin SiNWs, providing a solid basis for the development of advanced SiNW-derived field-effect transistors, sensors, and display applications.
