We study electronic quantum transport in graphene nanoribbon (GNR) networks on mesoscopic length scales. focus zigzag GNRs and investigate the conductance properties of statistical networks. To this end we use a density-functional-based tight-binding model to determine structure theory calculate properties. then introduce new efficient network decimation algorithm that reduces complexity generi...

In this paper, we present a physics-based analytical model of GNR FET, which allows for the evaluation of GNR FET performance including the effects of line-edge roughness as its practical specific non-ideality. The line-edge roughness is modeled in edge-enhanced band-to-band-tunneling and localization regimes, and then verified for various roughness amplitudes. Corresponding to these two regime...

In this work, a new interconnect structure is proposed for the first time where copper-carbon nanotube composite encapsulated by graphene barrier layers named here as (Cu-carbon) hybrid interconnects. The motivation behind to utilize enhanced conductivity of (Cu-CNT) and improved reliability copper-graphene (Cu-GNR) in order build better possible replacement copper interconnects near future VLS...

Experiments were conducted to examine soil nutrient dynamics under different farming systems and sources on maize yield. It was a split plot fitted into RCBD with three replicates. Main plots included two cropping (CS) (maize groundnut fallow): sub-plots; residue (GNR), (MZR), Cow dung (CD), pig manure (PGM); four composts; (PGM+MZR, PGM+GNR, CD+GNR CD+MZR) each at 5 t/ha; NPK 120 kg/ha, (Co) c...

PURPOSE To investigate gold nanorods (GNRs) as a contrast agent to enhance Doppler optical coherence tomography (OCT) imaging of the intrascleral aqueous humor outflow. METHODS A serial dilution of GNRs was scanned with a spectral-domain OCT device (Bioptigen, Durham, NC) to visualize Doppler signal. Doppler measurements using GNRs were validated using a controlled flow system. To demonstrate...

Magnetism in zigzag graphene nanoribbons (GNRs) has received enormous attention recently, due to the one-dimensional nature of this phenomenon, as well as its potential applications in the field of spintronics. In this work, we present a density functional theory (DFT) investigation of H-passivated GNRs on the (111) surface of the topological insulator Sb2Te3. We show that the chemical interact...

We study vibrations of singleand multi-layered rectangular graphene nanoribbons (GNRs) using molecular mechanics (MM) simulations by employing the MM3 potential. Two sets of boundary conditions are considered, namely, clamping atoms on either all four edges (CCCC) or on the two small edges (CFCF). Furthermore, we consider two scenarios for a single-layered GNR – one in which an interior atom is...

Abstract The electrical transport properties of a turbostratic multilayer graphene nanoribbon (GNR) with various number layers (1–8 layers) were investigated using field effect transistor single GNR channel. In the 5 or less, carrier mobility and I on /I off ratio in FETs improved by slightly increasing conductance layers, meaning that excellent semiconducting characteristic. improvement promot...

McCulloch-Pitts neuron structures are comprised of a number synaptic inputs and decision element, called soma. In this paper, we propose 5-bit Graphene Nanoribbon (GNR)-based DAC to fulfill the role summation element featuring programmable input weights. The proposed GNR-based relies on: (i) GNR unit current cells (ii) logic thermometric decoding block. Our implementation is based on mapping st...

The VITEK 2 card for gram-negative bacteria (bioMérieux,Marcy-l'Etoile, France) has been redesigned to improve the identification of fermenting and nonfermenting bacilli. Forty-seven biochemical tests, including 19 enzymatic tests, are present in the new card and interpreted in a kinetic mode. Final identification results are available within 10 h. The database allows the identification of 159 ...
