摘要:
A negative capacitance logic device includes a first field effect transistor (FET) and a second FET. The first FET is coupled between a power supply voltage and an output node, and the first FET includes a ferroelectric having a negative capacitance. The second FET is coupled between the output node and a ground voltage, and the second FET includes a ferroelectric having a negative capacitance. The negative capacitance logic differentiates an input voltage applied to an input node to provide an output voltage at the output node.
摘要:
The present invention relates to a bioactive carbon nanotube composite functionalized with a β-sheet polypeptide block copolymer by combination self-assembly, which shows excellent water dispersion, and has biological activity so as to be used as stimulus-responsive and adaptable biomaterials or in the manufacture of CNT-based electronic biosensor devices. In addition, the bioactive carbon nanotube composite can be used as a composition for delivery of a biological active material into cells. Further, the application of the interaction between a β-sheet peptide and a carbon-based hydrophobic material is expected to be useful for designing and developing an inhibitor for diseases caused by the abnormal folding of a protein and by biomacromolecular interactions (protein-protein, protein-DNA, and protein-RNA interactions etc).
