The band gap opening of bilayer graphene with one side surface adsorption F4-TCNQ is reported. doped shows p-type semiconductor characteristics. With a concentration 1.3 x 10(-10) mol/cm(2), the charge transfer between each molecule and 0.45e, built-in electric field, E(bi), layers could reach 0.070 V/A. F4-TCNQ-doped can be further modulated by an externally applied field (E(ext)). At 0.077 V/A, at Dirac point (K), DeltaE(K) = 306 meV, gap, E(g) 253 are around 71% 49% larger than those...
Multi-layer black phosphorus (m-BP) has been successfully incorporated in zinc oxide (ZnO) hollow spheres, thus forming hetero-structured ZnO-BP composites; a study performed on their properties reveals that the BP environmental stability can be significantly enhanced by introduction of ZnO, and sensors based composites exhibit high response, fast response behavior, outstanding selectivity, ultralow detection limit 1 ppb towards NO2 gas molecules. The ultrasensitive sensing performance is...
High angular momentum partial waves are indispensable in the numerical calculations of time-dependent Schrödinger equation (TDSE) for interaction between atoms and strong long-wavelength laser pulses. In these cases, widely-applied Lanczos propagator, used to solve TDSE, requires an extremely small time step be convergent. By splitting out centrifugal potential from whole Hamiltonian, we demonstrate that stiffness TDSE can reduced a rather large is allowed present Split-Lanczos propagator....
Indium-doped Cu2O thin films were fabricated on K9 glass substrates by direct current magnetron co-sputtering in an atmosphere of Ar and O2. Metallic copper indium disks used as the targets. X-ray diffraction showed that peaks could only be indexed to simple cubic Cu2O, with no other phases detected. Indium atoms exist In3+ Cu2O. Ultraviolet-visible spectroscopy transmittance samples was relatively high doping increased optical band gaps. The Hall effect measurement n-type semiconductors at...

The self-assembly of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) on graphene with coverage in the range 0.3−3 monolayers (MLs) is characterized by a DFT-based ab initio calculation method. For α modification mode, critical thickness 1 ML, growth PTCDA follows Stranski−Krastanov (SK) mode. β can form two complete MLs substrate.

The electronic and magnetic properties of MoS2 nanoribbons doped with 3d transitional metals (TMs) were investigated using first-principles calculations. Clean armchair (AMoS2NRs) are nonmagnetic semiconductors whereas clean zigzag (ZMoS2NRs) metallic magnets.

Light-emitting nonlinear optical molecules, especially those with large Stokes shifts and broad tunability of their emission wavelength, have attracted considerable attention for various applications including biomedical imaging fluorescent sensors. However, most chromophores only limited potential such due to small shifts, narrow fluorescence emissions, nonlinearity in highly polar solvents. In this work, we demonstrate that a two-photon absorbing stilbene chromophore exhibits absorption...
