Implementation of the Lattice Boltzmann Method on Heterogeneous Hardware and Platforms using OpenCL

Advances in Electrical and Computer Engineering, 2012
The Lattice Boltzmann method (LBM) has become an alternative method for computational fluid dynamics with a wide range of applications. Besides its numerical stability and accuracy, one of the major advantages of LBM is its relatively easy ...

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

Advanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC

Advanced Materials Interfaces, EarlyView.
We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...

Simulation of Magnetorheological Fluids Based on Lattice Boltzmann Method with Double Meshes

Journal of Applied Mathematics, 2012
In order to study the rheological characteristics of magnetorheological fluids, a novel approach based on the two-component Lattice Boltzmann method with double meshes was proposed, and the micro-scale structures of magnetorheological fluids in different

Application of Regularized Lattice Boltzmann Method for Incompressible Flow Simulation at High Reynolds Number and Flow with Curved Boundary

Journal of Fluid Science and Technology, 2011
Single-relaxation time lattice Boltzmann method lacks the required numerical stability for high Reynolds number flow simulations. The method is also restricted to Cartesian grid, making it difficult to be implemented in flow with curved boundary ...

Energy Band Alignment and Electro‐Optical Behavior of Nearly Unstrained Monolayer MoS2 Heterostructures With GaN

Advanced Materials Interfaces, EarlyView.
Large size (∼100 µm) monolayer MoS2 grown by LPI‐CVD on n‐GaN exhibit a high n‐type doping, very low strain, and a type‐I band alignment at MoS2/GaN interface. Photocurrent measurements under illumination with photon energies from ∼2 to ∼5 eV show superior electro‐optical performances of these MoS2/n‐GaN heterojunctions as compared to Ni/n‐GaN devices ...

Highly Anisotropic Quasi‐Direct Organic Metal Halide Hybrids: A Platform for Polarization‐Sensitive Optoelectronics

Advanced Materials Technologies, EarlyView.
One‐dimensional C4N2H14PbBr4 is shown to have a quasi‐direct electronic band structure and strongly anisotropic transport with polarized broadband emission. A GW/Bethe–Salpeter excited‐state force formalism, supported by polarized Raman and temperature‐dependent photoluminescence, identifies low–frequency Pb–Br phonons that drive ultrafast exciton self‐
