Photoemission measurements of Ultrathin SiO2 film at low take-off angles
The surface and interfacial analysis of silicon oxide film on silicon substrate is particularly crucial in the nano-electronic devices. For this purpose, series of experiments have been demonstrated to grow oxide film on Si (111) substrate. Then these films have been used to study the structure of the film by using X-ray photo emission spectroscopy (XPS) technique. The obtained results indicate...
متن کاملICAMMP 2011 International Conference on Advances in Materials and Materials Processing, Indian Institute of Technology Kharagpur, 9‐11 December, 2011 Study of ‘gold black’ coating as potential thin film solar cell efficiency enhancer
Efficiency enhancement of thin film solar cells was obtained using deposited gold-black particles as scattering centers. Gold black is shown to give a broad particle size distribution from nm to several microns. This results in plasma resonance-enhanced scattering and intensified local electric field over a broad spectrum. Initial experiments on thin film solar cells with gold black showed an i...
متن کاملQuantum size effects in Pb/Si„111... investigated by laser-induced photoemission
We use laser-induced photoemission spectroscopy at 6 eV photon energy to investigate quantum well states of epitaxial Pb films on Si 111 as function of film thickness. The binding energies of the quantum well states were found in good agreement with density-functional calculations for a freestanding Pb slab. An oscillation of the work function with a period of 2 ML was observed as a function of...
متن کاملBand gap and electronic structure of an epitaxial, semiconducting Cr0.80Al0.20 thin film.
Cr(1-x)Al(x) exhibits semiconducting behavior for x = 0.15-0.26. This Letter uses hard x-ray photoemission spectroscopy and density functional theory to further understand the semiconducting behavior. Photoemission measurements of an epitaxial Cr(0.80)Al(0.20) thin film show several features in the valence band region, including a gap at the Fermi energy (E(F)) for which the valence band edge i...
متن کاملSurface plasmon-driven hot electron flow probed with metal-semiconductor nanodiodes.
A continuous flow of hot electrons that are not at thermal equilibrium with the surrounding metal atoms is generated by the absorption of photons. Here we show that hot electron flow generated on a gold thin film by photon absorption (or internal photoemission) is amplified by localized surface plasmon resonance. This was achieved by direct measurement of photocurrent on a chemically modified g...
