Reflection anisotropy spectroscopy (RAS) is a non-destructive optical probe of surfaces that
is capable of operation within a wide range of environments. In this review we trace the …

To verify the effects of additional Li introduction on the Cs-O and Cs-NF 3 activation
processes of GaAs (100) photocathodes, Cs-Li-O and Cs-Li-NF 3 co-adsorption models of …

Low-energy electron microscopy (LEEM) was performed on p-Ga N samples during in situ
cesium deposition. LEEM images of electron reflectivity recorded as a function of the …

We show that Fresnel zone plates (ZPs), fabricated in a solid surface, can sharply focus
atomic Bose–Einstein condensates that quantum reflect from the surface or pass through the …

The honeycomb connection of carbon atoms by covalent bonds in a macroscopic two-
dimensional scale leads to fascinating graphene and solar cell based on graphene/silicon …

The electrical, magnetic and spin-filtering properties of Pd/Fe/GaAs (001) junctions are
investigated. The Pd/Fe thin layers are deposited on GaAs (001) surfaces both clean and …

Graphene two-dimensional carbon sheet with one atom thickness and one of the thinnest
materials in universe. However, pure Graphene sheets are limited for many applications …

Upon adsorption of Cs, the As-rich c (2× 8)/(2× 4) reconstruction of GaAs (001) is found to
exhibit an intense negative signal between 3 eV and 5 eV in the reflectance anisotropy …

The electronic properties of alkali metals (Cs and Na) deposited on the gallium-rich GaAs
(001 surface), have been investigated using synchrotron-radiation photoemission …

Surface optical anisotropy of GaAs (001) is extremely sensitive to adsorption of
electropositive and electronegative atoms. The oxygen‐induced experimental changes of …
