We study mechanisms of photoemission of hot electrons from plasmonic nanoparticles. We analyze the contribution of "transition absorption", i.e., loss of energy of electrons passing through the boundary between different materials, to the surface mechanism of photoemission. We calculate photoemission rate and transition absorption for nanoparticles...

A series of transition films from amorphous to microcrystalline silicon was successfully prepared by very high frequency plasma enhanced chemical vapor deposition(VHF-PECVD).Effects of gas pressure on the microstructure, photoelectric and transport properties of the films were investigated.The results indicate that increase of gas pressure improve ...
Ultraviolet photoelectron spectroscopy (UV-PES) is a well established technique that provides ionization energies of molecules in the gas phase. Flash vacuum thermolysis or vacuum gas-solid reactions coupled with UV-PES are especially suited for the generation and analysis of small amounts of short-lived species in real-time. These experimental dat...
We report the design and fabrication of InAs quantum dot gated transistors, which are normally-on, where the channel current can be switched off by laser illumination. Laser light at 650 nm with a power of 850 pW switches the channel current from 5 mu A to 2 pA, resulting in an on/off ratio of more than 60 dB. The switch-off mechanism and carrier d...
The exploitation of plasmonic local field enhancements to promote the local interactions between matter and optical fields motivates numerous researches. The objectives are to understand the mechanisms of plasmon-mediated interactions, and to realize molecularly- or atomically-precise nano-structures favouring such phenomena. We have developed a lo...
The potential of radiofrequency glow discharge optical emission spectrometry (rf-GD-OES) for the quantification and the solid-state speciation of metal oxide films has been investigated in this work. Two types of oxide coatings, an iron oxide film deposited on silicon and a chromate conversion coating (CCC), were studied at 700 Pa of pressure and 3...
