Atomically precise lateral modulation of a two-dimensional electron liquid in anatase TiO2 thin films

, 2017
Engineering the electronic band structure of two-dimensional electron liquids (2DELs) confined at the surface or interface of transition metal oxides is key to unlocking their full potential.

The surface structure of silver-coated gold nanocrystals and its influence on shape control

Nature Communications, 2015
Understanding the surface structure of metal nanocrystals with specific facet indices is important due to its impact on controlling nanocrystal shape and functionality. However, this is particularly challenging for halide-adsorbed nanocrystals due to the

Photonic band structures for surface waves on structured metal surfaces

Optics Express, 2005
Photonic band structures of surface modes on structured metal surfaces with periodic holes in them are obtained using the full-vectorial finite-difference time-domain method. Surface modes do exist for almost all investigated lattice types with any hole size, shape and depth. The results for a square lattice of wax-filled box holes in brass are also in

Propagation of the surface plasmon polaritons through gradient index and periodic structures

, 2010
We study the propagation of surface electromagnetic waves along the metallic surface covered by various layered dielectric structures. We show that strong radiative losses typical for the scattering of the surface wave can be considerably suppressed when

Structure and peculiarities of the (8 x n)-type Si(001) surface prepared in a molecular-beam epitaxy chamber: a scanning tunneling microscopy study

, 2009
A clean Si(001) surface thermally purified in an ultrahigh vacuum molecular-beam epitaxy chamber has been investigated by means of scanning tunneling microscopy. The morphological peculiarities of the Si(001) surface have been explored in detail.

Theoretical analysis of the electronic structure of the stable and metastable c(2x2) phases of Na on Al(001): Comparison with angle-resolved ultra-violet photoemission spectra

, 1998
Using Kohn-Sham wave functions and their energy levels obtained by density-functional-theory total-energy calculations, the electronic structure of the two c(2x2) phases of Na on Al(001) are analysed; namely, the metastable hollow-site structure formed ...

Surface States of the Topological Insulator Bi_{1-x}Sb_x

, 2008
We study the electronic surface states of the semiconducting alloy BiSb. Using a phenomenological tight binding model we show that the Fermi surface of the 111 surface states encloses an odd number of time reversal invariant momenta (TRIM) in the surface

Effects of whole‐soil warming on ecosystem carbon fluxes in an alpine grassland

Grassland Research
Background Global warming impacts ecosystem carbon exchange, thus altering the carbon sink capacity of terrestrial ecosystems. However, the response of ecosystem carbon fluxes to whole‐soil‐profile warming remains unclear.
