Surface Study by Energy-Filtered RHEED-AES.

High-Resolution Surface Plasmon Imaging of Gold Nanoparticles by Energy Filtered Transmission Electron Microscopy

We demonstrate the imaging capabilities of energy-filtered transmission electron microscopy at high energy resolution in the low energy-loss region, reporting the first direct image of a surface plasmon of an elongated gold nanoparticle at energies around 1 eV. Using complimentary model calculations performed within the boundary element method approach we can assign the observed results to the ...

CdTe-HgTe core-shell nanowire growth controlled by RHEED

We present results on the growth of CdTe-HgTe core-shell nanowires, a realization of a quasi-one-dimensional heterostructure of the topological insulator HgTe. The growth is a two step process consisting of the growth of single crystalline zinc blende CdTe nanowires with the vapor-liquid-solid method and the overgrowth of these wires with HgTe such that a closed shell is formed around the CdTe ...

Studies of LaA103{100} surfaces using RHEED and REM II: 5 X 5 surface reconstruction

For the first time, 5 X 5 surface reconstruction on annealed LaAIO3{100} surfaces is observed with reflection high-energy electron diffraction (RHEED) and reflection electron microscopy (REM). Most of the {100} surface areas are covered by the reconstructed layer. The presence of twin boundaries and protrusion contaminants on the surface has no influence on the formation of the reconstruction. ...

Phase transition on the Si(001) clean surface prepared in UHV MBE chamber: a study by high-resolution STM and in situ RHEED

The Si(001) surface deoxidized by short annealing at T ~ 925°C in the ultrahigh vacuum molecuar beam epitaxy chamber has been in situ investigated using high-resolution scanning tunneling microscopy (STM)and redegreesected high-energy electron diffraction (RHEED. RHEED patterns corresponding to (2 × 1) and (4 × 4) structures were observed during sample treatment. The (4 × 4) reconstruction aros...
