Title: Quantum oscillations in the surface excitations of ultrathin Mg(0001) films

Abstract

Using reflection electron energy-loss spectroscopy (EELS), we unveil a direct correlation between the thickness-dependent oscillatory charge spilling of quantum well states in epitaxial Mg(0001) films, and the linear dispersion coefficient of the monopole surface plasmon mode. In addition, the spectral intensities of the photoemission threshold excitation and multipole surface plasmon mode follow a similar but mutually anticorrelated quantum oscillatory pattern. We attribute these oscillatory features of the collective response to quantum oscillations in the ground-state charge-density profile, specifically its decay into the vacuum. Because the decay lengths can be controlled through the quantum-size effects and appropriate choice of the quantum-size boundary conditions, these insights are expected to be significant in the design of quantum-sized plasmonic devices.

Charge accumulation layers and surface states in ultrathin Cs,Ba/n-GaN(0001) interfaces

Journal Article Benemanskaya, G. V. ; Frank-Kamentskaya, G E ; Shmidt, N M ; ... - Journal of Experimental and Theoretical Physics

It is found that ultrathin cesium and barium coatings radically change the electronic properties of the surface and the near-surface region of epitaxial n-GaN(0001) layers. A charge accumulation layer serving as a quasi-two-dimensional electronic channel is first formed by adsorption on the surface of a semiconductor. It is revealed that photoemission from the accumulation layer is excited by visible light from the transparency region of GaN and is characterized by a high quantum yield. It is found that the photoemission thresholds h{nu}{sub s} and h{nu}{sub p} for s-and p-polarized excitation are equal to each other and correspond to the workmore »« less

Gapless Surface Dirac Cone in Antiferromagnetic Topological Insulator ${MnBi}_{2} {Te}_{4}$

Journal Article Hao, Yu-Jie ; Liu, Pengfei ; Feng, Yue ; ... - Physical Review. X

The recently discovered antiferromagnetic topological insulators in the Mn-Bi-Te family with intrinsic magnetic ordering have rapidly drawn broad interest since its cleaved surface state is believed to be gapped, hosting the unprecedented axion states with a half-integer quantum Hall effect. Here, however, we show unambiguously by using high-resolution angle resolved photoemission spectroscopy that a gapless Dirac cone at the (0001) surface of MnBi2Te4 exists inside the bulk band gap. Such an unexpected surface state remains unchanged across the bulk N´eel temperature, and is even robust against severe surface degradation, indicating additional topological protection. Through symmetry analysis and ab initio calculationsmore »« less

Electronic properties of lithium

Miscellaneous Watson, G M

The electronic properties of Li films grown on Be(0001) are studied using angle-resolved photoemission, inverse photoemission, and electron energy loss spectroscopy. The bulk bandstructure of Li is measured along the [Gamma] to N axis of the bulk Brillouin zone. The dispersion of the initial state with photon energy is found to be non-parabolic and is explained in terms of final state effects. An occupied bandwidth of 2.86 eV is measured and compared to self-energy calculations. A systematic discrepancy between calculated and measured quasiparticle widths is identified and discussed. The surface plasmon for thick films is measured and a negative dispersionmore »« less
Entangled two-plasmon generation in carbon nanotubes and graphene-coated wires

Journal Article Muniz, Y. ; Abrantes, P. P. ; Martín-Moreno, L. ; ... - Physical Review. B

Here, we investigate the two-plasmon spontaneous decay of a quantum emitter near single-walled carbon nanotubes (SWCNTs) and graphene-coated wires (GCWs). We demonstrate efficient, enhanced generation of two-plasmon entangled states in SWCNTs due to the strong coupling between tunable guided plasmons and the quantum emitter. We predict two-plasmon emission rates more than twelve orders of magnitude higher than in free space, with average lifetimes of a few dozen nanoseconds. Given their low dimensionality, these systems could be more efficient for generating and detecting entangled plasmons in comparison to extended graphene. Indeed, we achieve a tunable spectrum of emission in GCWs, wheremore »« less

Evidence for the presence of the multipole plasmon mode on Ag surfaces

Journal Article Moresco, F ; Rocca, M ; Zielasek, V ; ... - Physical Review, B: Condensed Matter

Collective surface electronic excitations on Ag(111) and Ag(110) have been studied by energy-loss-spectroscopy LEED. The data allow separation of the contribution to the loss intensity due to monopole and to multipole surface plasmons, thus demonstrating the existence of the latter mode also on noble-metal surfaces. Multipole plasmons are therefore a general property of the optical response of metal surfaces whenever the charge-density profile at the interface is not too abrupt. {copyright} {ital 1996 The American Physical Society.}
