What makes things twist? Crystallization and chirality have been entangled since Pasteur's observations on chiral tartaric acid crystals, yet there is still limited understanding of how compounds form crystal morphologies. For example, although a seed can promote particular handedness, it not clear why such seeds do so with 100% efficiency. Ben-Moshe et al. examined nanocrystals tellurium grown from solution using various electron microscopy diffraction techniques (see the Perspective by...
Van der Waals (vdW) heterostructures combining layered ferromagnets and other 2D crystals are promising building blocks for the realization of ultracompact devices with integrated magnetic, electronic, optical functionalities. Their implementation in various technologies depends strongly on development a bottom-up scalable synthesis approach allowing realizing highly uniform well-defined interfaces between different 2D-layered materials. It is also required that each material component...
Abstract Orthogonal to guided growth of nanoparticle (NP) crystals using DNA or supramolecules, a trace amount polymeric impurities (<0.1 wt.%) leads reproducible, rapid 3D NP in solution and on patterned substrates with high yield. When polymers preferentially precipitate the surfaces, small clusters form serve as nuclei for crystal dilute solutions. This precipitation-induced crystallization process is applicable range polymers, resultant 3-D are tunable by varying additives loading,...
Semiconductor nanowires (NWs) are promising candidates for use in electronic and optoelectronic applications, offering numerous advantages over their thin film counterparts. Their performance relies heavily on the quality of contacts to NW, which should exhibit ohmic behavior with low resistance be formed a reproducible manner. In case heterostructure NWs high-mobility applications that host two-dimensional electron gas, particularly challenging implement since NW core constituting...

(In,Ga) alloy droplets are used to catalyse the growth of (In,Ga)As nanowires by molecular beam epitaxy on Si(111) substrates. The composition, morphology and optical properties these can be tuned employed elemental fluxes. To incorporate more than 10% In, a high In/(In+Ga) flux ratio above 0.7 is required. We report maximum In content almost 30% in bulk for an 0.8. However, with increasing fl ux ratio, nanowire length diameter notably reduced. Using photoluminescence cathodoluminescence...
