Abstract: A method comprises forming a first structured pattern having a first line width on a substrate. A polymer brush is deposited on the structured pattern, which is annealed a first time at a first temperature and then annealed a second time at a second temperature higher than the first temperature. A block copolymer is deposited on the structured pattern and polymer brush, and aligned first block and second block structures are formed on the structured pattern and polymer brush. The first block structures and portions of the polymer brush and the structured pattern positioned beneath the first block structures are removed, and the substrate between the second block structures is exposed. The second block structures are then removed to form a second structured pattern in the substrate having a second line width, the second line width being smaller than the first line width.

Abstract: A method of forming a patterned media includes constraining growth of magnetic grains in a down-track direction without constraining the growth in a radial direction to cause the magnetic grains to align in rows extending in the radial direction. The patterned media may allow for data track radial width to be defined independent of grain size.

Abstract: A data storage medium may have increased data capacity by being configured with first and second patterned pedestals that are each separated from a substrate by a seed layer. A first polymer brush layer can be positioned between the first and second patterned pedestals atop the seed layer and a second polymer brush layer may be positioned atop each patterned pedestal. The first and second polymer brush layers may be chemically different and a block copolymer can be deposited to self-assemble into separate magnetic domains aligned with either the first or second polymer brush layers.

Abstract: A DNA sequencing device and methods of making. The device includes a pair of electrodes having a spacing of no greater than about 2 nm, the electrodes being exposed within a nanopore to measure a DNA strand passing through the nanopore. The device can be made by depositing a conductive layer over a sacrificial channel and then removing the sacrificial channel to form the electrode gap.

Abstract: A DNA sequencing device and related methods, wherein the device includes a substrate, a nanochannel formed in the substrate, a first electrode positioned on a first side of the nanochannel, and a second electrode. The second electrode is positioned on a second side of the nanochannel opposite the first electrode and is spaced apart from the first electrode to form an electrode gap that is exposed in the nanochannel. At least a portion of first electrode is movable relative to the second electrode to decrease a size of the electrode gap.

Abstract: Apparatus and methods to sequence DNA. A DNA sequencing device includes a passage, a first electrode, and a second electrode. The passage has a width and a length. The first and second electrodes are exposed within the passage and spaced apart from each other to form an electrode gap. The electrode gap is no greater than about 2 nm. The DNA sequencing device is operable to measure with the first and second electrodes a change in electronic signal in response to nucleotides of a DNA strand passing through the electrode gap.
