摘要： Methods of spatially directing the orientation and placement of multiple block copolymer (BCP) domains on isolated regions of a substrate are described. The methods involve epitaxially directing the assembly of BCP domains using spatial boundaries between regions with different surface composition, formed at the edges of isolated chemical regions on a background chemistry. Multiple vertical domains of BCP order on the isolated region, self-aligned in a direction parallel to edges of the isolated region. In some embodiments, vertical domains order on multiple isolated regions of a first chemistry of a chemical contrast pattern with horizontal domains on the regions of a second (background) chemistry of the chemical contrast pattern. Also provided herein are compositions resulting from the methods.

摘要： Flexible transistors and electronic circuits incorporating the transistors are provided. The flexible transistors promote heat dissipation from the active regions of the transistors while preserving their mechanical flexibility and high-frequency performance. The transistor designs utilize thru-substrate vias (TSVs) beneath the active regions of thin-film type transistors on thin flexible substrates. To promote rapid heat dissipation, the TSVs are coated with a material having a high thermal conductivity that transfers heat from the active region of the transistor to a large-area ground.

摘要： Hyperspectral resonant cavity imaging spectrometers and imaging systems incorporating the resonant cavity spectrometers are provided. The spectrometers include an array of photodetectors based on photosensitive semiconductor nanomembranes disposed between two dielectric spacers, each of the dielectric spacers having a thickness gradient along a lateral direction, such that the resonant cavity height differs for different photodetectors in the array.

摘要： Photoreceptor scaffolds and scaffold systems including the photoreceptor scaffolds are described herein. The scaffolds and scaffold systems can be used for transplantation of organized photoreceptor tissue, with or without RPE, which may improve grafted cell survival, integration, and functional visual rescue. Particularly, the photoreceptor scaffold is structured from a biocompatible film, patterned with an array of unique through-holes having a curvilinear cell receiver and at least one cell guide channel.

摘要： Light-emitting devices having a multiple quantum well (MQW) diode structure and methods of making and using the devices are provided. The devices include aluminum nitride/aluminum oxide bilayers on their hole injection layers. The bilayers improve the energy efficiency of the devices, with respect to devices that lack the bilayers or that include only a layer of aluminum oxide on their hole injection layers.
