We tried to establish models that predict systemic recurrence in breast cancer by selecting marker clones with DNA copy number alterations (CNAs) using an array comparative genomic hybridization (CGH). Array CGH containing 4,044 human bacterial artificial chromosome clones was used to assess CNAs in 62 primary breast cancer tissues from 31 patients with(More)
Until now, acrylates have been the monomers of choice for use for step and flash imprint lithography ͑SFIL͒ etch barrier formulations, in part because of the commercial availability of silicon-containing acrylates ͑necessary for etch resistance͒, together with their low viscosities and capability for rapid photopolymerization. However, despite many(More)
We fabricated multi-layered graphene/MoS2 heterostructured devices by positioning mechanically exfoliated bulk graphite and single-crystalline 2H-MoS2 onto Au metal pads on a SiO2/Si substrate via a contamination-free dry transfer technique. We also studied the electrical transport properties of Au/MoS2 junction devices for systematic comparison. A previous(More)
Cu and Cu2O nanoparticles were fabricated in polyimide by curing the stacked polyamic acid/Cu/polyamic acid on Si wafer and post heat treatment. Nanoparticle distribution in polyimide (a monolayer of vertically aligned nanoparticles or the randomly dispersed nanoparticles) can be controlled by changing the reactivity of Cu with PAA and curing atmosphere.(More)
Unsuppressed carrier scattering from the underlying substrate in a layered two-dimensional material system is extensively observed, which degrades significantly the performance of devices. Beyond the material itself, understanding the intrinsic interfacial and surficial properties is an important issue for the analysis of a high-κ/MoS2 heterostructure.(More)
We report on the transport and magnetic properties of graphene annealed at 800 °C under an Ar atmosphere. Temperature dependence of resistivity of the annealed graphene shows that the ferromagnetic Curie temperature can be observed from the magnetoimpurity model. The Curie temperature is 220 K for the annealed graphene.
We report a highly stable p-type doping for single walled carbon nanotubes using an electrochemical method. The Raman spectroscopy showed the upshift of the G-band when the applied potential increased. Furthermore, the carbon core level shifted as much as 0.14 eV in binding energy of XPS measurement, which is an evidence of p-type doping with a Fermi level(More)
The effects of template surface composition on fluorinated surfactant segregation were investigated for imprint lithography with photopolymerizable vinyl ether formulations. Heptadecafluoro-1,1,2,2-tetrahydrodecyl vinyloxy-methyloxy dimethylsilane, containing a vinyl ether group, was employed as the surfactant, and blanket templates were pressed onto the(More)
Nanofloating gate memory ͑NFGM͒ devices using In 2 O 3 nanoparticles as charge storages embedded in polyimide gate insulator were fabricated. Self-assembled In 2 O 3 nanoparticles were formed inside the polyimide matrix as a result of chemical reactions between indium ions and polymer precursors. The average diameter and the particle density were 7 nm and 6(More)
The electrical characteristics of SiC nanocrystal nonvolatile-memory devices with variable oxide and crested tunnel barriers consisting of a SiO2/Si3N4/SiO2 (ONO) and a Si3N4/SiO2/Si3N4 (NON) layer, respectively, were investigated. The equivalent oxide thickness of the ONO and NON tunnel barriers were about 5.6 nm and 5.2 nm, respectively. When the +/- 13 V(More)
