Abstract: A light-emitting device including: a substrate; a light-emitting diode; and an optical resonance layer to resonate light emitted from the light-emitting diode. The optical resonance layer includes a first layer, including a polysilsesquioxane-based copolymer. A linking group connecting two different silicon (Si) atoms of the polysilsesquioxane-based copolymer can be —O—, or a substituted or unsubstituted C1-C30 alkylene group.

Abstract: A thin-film transistor comprises a semiconducting layer comprising a semiconducting material selected from Formula (I) or (II): wherein X, R1, R2, R3, R4, R5 a, b, and n are as described herein. Semiconducting compositions of Formula (I) or (II) are also described.

Abstract: The organic TFT includes: a gate electrode; source and drain electrodes insulated from the gate electrode; an organic semiconductor layer insulated from the gate electrode and electrically connected to the source and drain electrodes; an insulating layer insulating the gate electrode from the source and drain electrodes and the organic semiconductor layer; and a self-assembly monolayer (SAM) included between the insulating layer and the organic semiconductor layer. A compound forming the SAM has at least one terminal group selected from the group consisting of an unsubstituted or substituted C6-C30 aryl group and an unsubstituted or substituted C2-C30 heteroaryl group. The organic TFT is formed by forming the above-described layers and forming the SAM on the insulating layer before the organic semiconductor layer and source and drain electrodes are formed.

Abstract: The present invention is directed to a memory device having very high storage density capability. In general, the memory device includes an array of individual memory cells which store information that is assigned a value based on the molecular contents of the memory cell. In a preferred embodiment, the molecules utilized for storing information in the memory cells may be single-strand polynucleotides, for instance single-strand oligonucleotides of between about 5 and about 20 monomer units. The present invention is also directed to methods and systems useful for writing and reading the molecular-based memory devices. In particular, the devices may be written and read via modified atomic force microscopy processes.
