Low-pressure chemical vapor deposition and stacked multiple transfer techniques have been developed to achieve high-density aligned carbon nanotubes and high-performance submicron nanotube field- effect transistors have been further demonstrated. This platform holds great potential for high performance nanoelectronics and analog/RF applications.

Water-soluble monodisperse single core nanocrystals (e.g., iron oxide nanoparticles and semiconductor quantum dots) as well as magnetic–optical hybrid nanoparticles have been synthesized using the amphiphilic copolymer poly(ethylene oxide)-b-poly (γ-methacryl- oxypropyltrimethoxysilane) (PEO-b-PγMPS) by enhancing ligand exchange through aging. Multi-core clustered nanoparticles have been generated using the same copolymer by minimizing the ligand exchange by not aging. The resulting multi-core clustered nano- particles exhibit enhanced magnetic and optical properties, and have greater capacities for biomedical applications.

Using in situ scanning tunneling microscopy (STM) and angle- resolved photoemission spectroscopy (ARPES), we show that ultrathin Sb2Te3 films grown layer-by-layer by molecular beam epitaxy (MBE) on Si(111) are atomically smooth, single-crystalline topological insulators.

The quantitative analysis of low temperature micro-photoluminescence spectra of around 100 nanowires reveals that each nanowire exhibits its own individual spectrum. A significant fraction of nanowires exclusively emits at energies corresponding to either surface- donor-bound or free excitons, demonstrating that optical properties of individual nanowires are determined by the presence and location of a few impurity atoms alone.

Direct laser patterning of superhydrophobic silicone nanofilaments is investigated. Processing with a focused laser beam at 355 nm allows selective removal of the coating which leads to contrasting wettabilities of the substrate.
