Electrical and optoelectronic properties of few-layer black phosphorus field-effect transistors are investigated through spatial-, polarization-, gate-, bias-dependent photocurrent measurements.
An accurate density-functional method is used to study systematically half-metallic ferromagnetism and stability of zincblende phases 3d-transition-metal chalcogenides. The CrTe, CrSe, VTe are found be excellent ferromagnets with large gaps (up 0.88 eV). They mechanically stable approximately 0.31-0.53 eV per formula unit higher in total energy than the corresponding nickel-arsenide ground-state phases, therefore would grown epitaxially form films layers thick enough for spintronic applications.
We investigate the photocurrent generation mechanisms at a vertical p-n heterojunction between black phosphorus (BP) and molybdenum disulfide (MoS2) flakes through polarization-, wavelength-, gate-dependent scanning measurements. When incident photon energy is above direct band gap of MoS2, response demonstrates competitive effect MoS2 BP in junction region. In contrast, if below but BP, exhibits same polarization dependence as that BP-metal junction, which nearly parallel to channel. This...
We report high-performance WSe2 phototransistors with two-dimensional (2D) contacts formed between degenerately p-doped and undoped channel. A photoresponsivity of ∼600 mA/W a high external quantum efficiency up to 100% fast response time (both rise decay times) shorter than 8 μs have been achieved concurrently. More importantly, our phototransistor exhibits specific detectivity (∼1013 Jones) in vacuum, comparable or higher commercial Si- InGaAs-based photodetectors. Further studies shown...
We investigate the wavelength- and polarization-dependence of photocurrent signals generated at few-layer MoS2-metal junctions through spatially resolved measurements. When incident photon energy is above direct bandgap MoS2, maximum response occurs for light polarization direction parallel to metal electrode edge, which can be attributed photovoltaic effects. In contrast, if below maximized when polarized in perpendicular indicating different generation mechanisms. Further studies show that...

The full-potential augmented plane wave plus local orbital method within density-functional theory is used to predict that MnBi in the zinc-blende structure a true half-metallic ferromagnet with magnetic moment of $4.000{\ensuremath{\mu}}_{B}$ per formula unit. This contrasts phase MnAs, which only nearly ferromagnet. ferromagnetic behavior found be robust against compressive volume changes up 15%, its stability being enhanced by relativistic shift valence s state energy levels. Zinc-blende...
A controlled and scalable multistep purification method has been developed to remove iron impurity nonnanotube carbon materials from raw single-walled nanotubes (SWNTs) produced in the HiPco (high-pressure CO) process. In this study, nanoparticles, coated by carbon, are exposed oxidized multiple step oxidation at increasing temperatures. To avoid catalytic oxide of nanotubes, is deactivated reaction with C2H2F4 or SF6. The fluorides removed a Soxhlet extraction 6 M HCl solution. purity...
Utilizing aligned carbon nanotube arrays grown from chemical vapor deposition, we present a highly scalable route toward the formation of ribbons and ultrathin transparent films directly vertically single-walled (SWNT carpets). To "lay-over" nanotubes to form film, use roller which acts compress film preserve alignment within film. As demonstrate, can control nanotube-catalyst interaction, leading efficient transfer virtually any host substrate by following growth with controlled H2O etch....
A scalable and facile approach is demonstrated where as-grown patterns of well-aligned structures composed single-walled carbon nanotubes (SWNT) synthesized via water-assisted chemical vapor deposition (CVD) can be transferred, or printed, to any host surface in a single dry, room-temperature step using the growth substrate as stamp. We demonstrate compatibility this process with multiple transfers for large-scale device specifically tailored pattern fabrication. Utilizing transfer approach,...
An investigation into the optimal growth of single-walled carbon nanotubes (SWNTs) in vertical arrays, or carpets, is presented utilizing atomic hydrogen catalyst activation with hot filament chemical vapor deposition. Using acetylene decomposition over Fe catalyst, we study effect oxidant-assisted using O2, CO2, and H2O. Whereas trace amounts O2 result lack any catalytic activity, CO2 H2O are found to dramatically enhance lifetime. On basis saturation oxidant concentration for both H2O,...
Silver nanowires have been widely adopted as nanofillers in composite materials used for various applications. Electrical and thermal properties of these composites are critical proper device operation, highly depend on transport through the their contacts, yet studies silver limited to one or two samples no solid data reported individual contacts. Through systematic measurements different sizes, we show that Lorenz number increases with decreasing wire diameter has a higher value at...

Abstract Skeletal muscle weight loss is accompanied by small fiber size and low protein content. Alpha-ketoglutarate (AKG) participates in nitrogen metabolism. The effect of AKG on skeletal hypertrophy has not yet been tested, its underlying mechanism to be determined. In this study, we demonstrated that (2%) increased the gastrocnemius diameter mice. Our vitro study also confirmed dose synthesis C2C12 myotubes, which could effectively blocked antagonists Akt mTOR. effects were independent...

Graphene possesses extraordinary properties that promise great potential in biomedicine. However, fully leveraging these requires close contact with the cell surface, raising concern of unexpected biological consequences. Computational models have demonstrated graphene preferentially interacts cholesterol, a multifunctional lipid unique to eukaryotic membranes. Here we demonstrate an interaction between and cholesterol. We find increases membrane cholesterol potentiates neurotransmission,...
The last two decades have seen tremendous progress in quantitative understanding of several major phonon scattering mechanisms (phonon-phonon, phonon-boundary, phonon-defects), as they are the determinant factors lattice thermal transport, which is critical for proper functioning various electronic and energy conversion devices. However, roles another mechanism, electron-phonon (e-ph) interactions, remain elusive. This largely due to lack solid experimental evidence effects e-ph conductivity...
Oxidative stress-induced vascular endothelial cell (VEC) injury is a major mechanism in the initiation and development of atherosclerosis. Lunasin, soybean-derived 43-aa peptide, has been previously shown to possess potent antioxidant anti-inflammatory activities other than its established anticancer activities. This study investigated effects lunasin on protecting VECs from oxidative damage inhibiting atherosclerotic plaque progression apolipoprotein E-deficient (ApoE
