A method for laying out arrays of components in programmable 2D arrangements with nanometer-scale precision is needed the manufacture high density nanoelectronic circuitry. We report programmed self-assembly gold prototype into closely packed rows precisely defined inter-row spacings by situ hybridization DNA-functionalized to a preassembled DNA scaffolding on surface. This approach broadly applicable nanoscale integrated circuits logic, memory, sensing, and other applications.

Regular 2D arrays of multiple types nanocomponents were constructed by self-assembly to DNA scaffolding with alternating rows sequence-encoded hybridization sites. Different-sized Au particles coated complementary one the sites bound scaffolding, producing two a 32-nm inter-row spacing. These results demonstrate potential for using self-assemble complex components nanometer-scale precision.

Negative differential resistance (NDR) is reported for a bilayer molecular junction. The system comprised of Hg–alkanethiol//arenethiol–Au junction formed by bringing into contact tetradecanethiol self-assembled monolayer (SAM)-coated drop Hg with the surface an oligo(phenylene-ethynylene) SAM on Au. Persistent, reproducible NDR observed in current–voltage characteristics peak-to-valley ratios as high 4.5 at room temperature. These results open promising line investigation structure/function...

Experimental results on the electrical characteristics of Hg-alkanethiol∕arenethiol-Au molecular junctions are used to develop a physical model for hysteretic negative-differential resistance (NDR) these, and possibly other, metal-molecule-metal junctions. The dependence room-temperature current-voltage characteristic sweep direction rate is examined. Based several specific electronic behaviors, it concluded that NDR caused by slow charge capture (reduction or oxidation) during forward...

Polarized catadioptric optics systems are an emerging solution for virtual reality (VR) head mounted displays (HMD). A good VR optical system should have a large pupil volume to tolerate multiple interpupillary distances and accommodate eye rotation as the user scans across field of view (FOV).

We present a high‐performing polarizing beam splitter for augmented reality applications using newly developed 3M™ Polarized Beam Splitter (PBS) film. It has very low light leaks which are largely independent of incident side. At the same time, high efficiency is maintained with 96% transmission and 98% reflection integrated over an f/2 cone. Comparisons made to wire‐grid PBS.

Polarized catadioptrics (i.e., folded optics, pancake lenses) offer increased resolution and reduced aberrations across a wider field‐of‐view, in smaller physical package than conventional refractive optics for virtual reality (VR) head‐mounted display applications.
