Structural dataset for Si(1 1 0) and Si(17 15 1) surface models and related calculated STM images.

In this work we present the novel atomic models of the (1 1 0)-(16 × 2), (1 1 0)-(8 × 10), (1 1 0)-(5 × 8) and (17 15 1)-(2 × 1) silicon surface reconstructions. The models are also valid for respective germanium surfaces. The dataset reports atomic coordinates for each surface reconstruction and related calculated bias-dependent scanning tunneling microscopy (STM) images.

Atomic and electronic structure of the Si(331)-(12 1) surface.

We report on the investigation of the atomic and electronic structures of a clean Si(331)-(12 × 1) surface using a first-principles approach with both plane wave and strictly localized basis sets. Starting from the surface structure proposed by Zhachuk and Teys [Phys. Rev.

Noble metal nanocrystals at the surface of nitride semiconductors: synthesis, deposition and surface characterization.

Currently an extensive range of noble metal colloidal nanocrystals (NCs) can be readily produced by diverse chemical methods. These nanomaterials present novel physical properties and can be regarded as building blocks to the nanofabrication of smaller, energy efficient and faster devices. Moreover, when these NCs are deposited on the surface of luminescent semiconductors, as it is the case of GaN-based heterostructures, exciton coupling with the metal plasmons may occur.
