A light emitting device includes: a substrate; a first electrode and a second electrode provided at a distance from each other on the substrate and extending in one direction; a plurality of light emitting diodes provided between the first electrode and the second electrode, and connected to the first electrode and the second electrode; and a residual pattern provided between at least one of the plurality of light emitting diodes and the substrate.

Systems, methods and tools for the synthesis of products via mechanosynthesis are disclosed, including a set of atomically-precise tips and associated reactions, methods for determining build sequences for workpieces, exemplary build sequences, and methods for creating new reactions, build sequences, and tips.

A method is provided for forming structures upon a substrate. The method comprises: depositing fluid onto a substrate so as to define a wetted region, the fluid containing electrically polahzable nanoparticles; applying an alternating electric field to the fluid on the region, using a first electrode and a second electrode, so that a plurality of the nanoparticles are assembled to form an elongate structure extending from the first electrode towards the second electrode; and removing the fluid such that the elongate structure remains upon the substrate.

A nanostructure is provided that in one embodiment includes a cluster of cylindrical bodies. Each of the cylindrical bodies in the cluster are substantially aligned with one another so that their lengths are substantially parallel.

Each cluster of cylindrical bodies may have a width dimension ranging from 0.2 microns to 5.0 microns, and a length greater than 5.0 microns. In some embodiments, the cylindrical bodies are composed of tungsten disulfide (WS2). In another embodiment the nanolog is a particle comprised of external concentric disulfide layers which encloses internal disulfide folds and regions of oxide. Proportions between disulfide and oxide can be tailored by thermal treatment and/or extent of initial synthesis reaction.
