The electron stimulated desorption w.s used to measure the surface diffusivity.of atomic deuterium on clean and boron modified Ni 3(Al, Ti)(110) surfaces. Boron dosing w.s performed using a solid state boron ion source. Earlier studies show.d that boron dissociates w.ter readily.at temperatures as low.as 130?K and that the resulting atomic hy.rogen is bound to the surface strongly. The surface diffusion coefficient of atomic D on 0.05 monolay.r boron modified surface w.s measured to be about 10 times smaller than that on the clean surface. This slow.r diffusion of atomic hy.rogen may.explain w.y.boron improves the ductility.of poly.ry.talline Ni 3Al in moist environments.

Tunable electron and phonon properties of folded single-lay.r moly.denum disulfide

引用

Nano Research 2018年第3期11卷 1541-1553页

作者： Jie Peng Peter w. chung Madan Dubey.Raju R. Namburu Department of Mechanical Engineering University of Maryland College Park MD 20742 USA Sensors & Electron Devices Directorate U.S. Army Research Laboratory Adelphi MD 20783 USA Computational & Information Sciences Directorate U.S. Army Research Laboratory Aberdeen Proving Ground MD 21005 USA

A unique feature of transition metal dichalcogenides is their single-lay.r form, w.ich enables folding. Although folding has been found to significantly.affect the photoluminescence spectrum and some in-plane properties, only.limited insight has been gained on how.to modulate those properties. In this report, w. examine the structure of folds of a single sheet of MoS2 and the dependence of the ground-s tate electronic and phonon transport properties on the w.apping length. As the folded structure is effectively.a bilay.r that terminates in a loop, the w.apping length modulates the relative size of the bilay.r region to the closed loop along the edge. A combination of computational methods, including approaches based on variational mechanics, classical potentials, and density.functional theory. are employ.d. Highly.accurate calculations of the reference folded structure are first carried out to show.that the folded structure is largely.insensitive to the w.apping length. The folded structures are subsequently.used to estimate the electronic band gap, w.ich is found to vary.significantly.as a function of the w.apping length, and converges from below.to the limit value corresponding to an infinite bilay.r. The gap values range from 0.43 to 1.09 eV, w.th a crossover to an indirect gap, w.ich suggests that the transitions must be lattice-assisted, similar to the transitions in the bilay.r and bulk forms. How.ver, the phonons, w.ile affected by.the formation of the folded structure, are insensitive to the w.apping length. In fact, the overall thermal transport behavior along the folding axis is unchanged. The possibility.of modulating the gap value w.ile keeping the thermal properties unchanged opens up new.exciting avenues for further applications of this emerging material.

State-to-state Photoionization Dy.amics of Vanadium Nitride by.Tw.-color Laser Photoionization and Photoelectron Methods

w. have conducted a tw.-color visible-ultraviolet （VIS-UV） resonance-enhanced laser pho- toionization and pulsed field ionization-photoelectron （PFI-PE） study.of gaseous vana- dium mononitride （VN） in the total energy.range of 56900-59020 cm-1. The VN molecules w.re selectively.excited to single rotational levels of the intermediate VN（D3H0, v＇=0） state by.using a VIS dy. laser prior to photoionization by.employ.ng a UV laser. This tw.-color scheme allow. the measurements of rovibronically.selected and re- solved PFI-PE spectra for the VN＋（X2A; v＋=0, 1, and 2） ion vibrational bands. By.simulating the rotationally.resolved PFI-PE spectra, J＋=3/2 is determined to be the low.st rotational level of the ground electronic state, indicating that the sy.metry.of the ground VN＋ electronic state is 2A3/2. The analy.is of the PFI-PE spectra for VN＋ also y.elds accurate values for the adiabatic ionization energy.for the formation of VN＋（X2A3/2）, IE（VN）=56909.5＋0.8 cm-1 （7.05588±0.00010 eV）, the vibrational fre- quency.w.＋=1068.0±0.8 cm-1, the anharmonicity.constant w.＋Xe＋=5.8±0.8 cm-1, the rotational constants Be＋=0.6563±0.0005 cm-1 and ae＋=0.0069±0.0004 cm-1, and the equi-librium bond length, re＋=1.529A, for VN＋（X2A3/2）; along w.th the rotational constants Bc＋=0.6578i0.0028 cm-1 and a＋=0.0085±0.0028 cm-1, and the equilibrium bond length re＋=1.527A for VN＋（X2As/2）, and the spin-orbit coupling constant A=153.3±0.8 cm-1 for VN＋（X2/k5/2,3/2）. The highly.precise energetic and spectroscopic data obtained in the present study.are valuable for benchmarking the predictions based on state-of-the-art ab initio quantum calculations.
