摘要： Some embodiments include a semiconductor device having a stack structure including a source comprising polysilicon, an etch stop of oxide on the source, a select gate source on the etch stop, a charge storage structure over the select gate source, and a select gate drain over the charge storage structure. The semiconductor device may further include an opening extending vertically into the stack structure to a level adjacent to the source. A channel comprising polysilicon may be formed on a side surface and a bottom surface of the opening. The channel may contact the source at a lower portion of the opening, and may be laterally separated from the charge storage structure by a tunnel oxide. A width of the channel adjacent to the select gate source is greater than a width of the channel adjacent to the select gate drain.

摘要： An optical device for transforming an input light distribution from an LED light source to provide an omni-directional output light distribution for solid-state lighting is disclosed. The optical device has a conical form, comprising first and second coaxial cones of different refractive index, defined by coaxial inner and outer cone surfaces, which converge from a cone base to a rounded tip at the apex. Preferably, each of the inner and outer cone surfaces comprises a plurality of conical facets defining a grating structure. The inner cone, i.e. air cavity, is directly coupled to an LED emitter area. Cone angles and spacings of conical facets, defining inner and outer gratings, are tailored to reshape a predetermined input light distribution. Apertures assist in heat dissipation. A lightweight, compact device with high transmission efficiency can be manufactured at low cost by one-step injection molding from an optical-grade polymer, such as PMMA.

摘要： The invention relates to a carbon nanoring and a method for preparing the same. The carbon nanoring according to the present invention is composed of monolayered or multilayered coaxial carbon rings, wherein the carbon ring has a structure similar to that of a closed ring system formed by graphite sheet being rolled, and each of an axial dimension and a radial dimension of the carbon nanoring is nanoscale with the axial dimension being smaller than the radial dimension. The invention further provides a method for preparing the above carbon nanoring including calcinating in an inert atmosphere or a reducing atmosphere a layered double hydroxides obtained by intercalating a long-chain alkyl anion and a carbon source molecule, growing a carbon nanoring within a confined region between layers under the catalysis of the metal element in layers, and removing the metal and the metal oxide by dissolving in an acid to obtain the carbon nanoring. By using this method, the carbon nanoring can be effectively controlled in terms of the axial dimension, the radial dimension, and the number of layers of the carbon ring thereof. The carbon nanoring provided by the present invention has the nano-ring shaped structure and the excellent properties of carbon materials, as well as more edge carbons and dangling bonds, and thus it has broad application prospects in such field as nanodevices, energy storage and sensing.
