Deux méthodes de synthèse chimique, relevant de l'approche bottom-up, sont mises en oeuvre pour élaborer des nanocristaux (NC) de sulfure de cadmium (CdS) : les croissances (i) par source unique de précurseur et (ii) par voie micro-ondes. Ces deux techniques, complémentaires dans la gamme de tailles obtenues, permette…
We investigate the graphene-impurity interaction problem by combining experimental - scanning tunneling microscopy (STM) and spectroscopy (STS) - and theoretical - Anderson impurity model and density functional theory (DFT) calculations - techniques. We use graphene on the SiC(000-1)(2x2)_C reconstruction as a model s…

The ITRS roadmap specifies wafer overlay control as one of the major tasks for the sub 40 nm nodes in addition to CD control and defect control. Wafer overlay is strongly dependent on mask image placement error (registration errors or Reg errors)1. The specifications for registration or mask placement accuracy are sig…
We have seen that lateral resolution in conventional optical microscopy is limited by light diffraction. This means that objects smaller than approximately half the wavelength of light (λ/2) cannot be properly resolved. Near-field optical microscopy overcomes the diffraction limit by collecting the near-field light, w…
This procurement specification covers aircraft quality self-locking nuts for wrenching (hex, spline) and anchor (plate, gang channel, shank) types of nuts made from a corrosion and heat resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001. Tension height nuts having overa…

This paper describes the effects and the accelerated ageing of polymer, ceramic and glas insulators under artificial tropical climate. A comparison of the surface leakage current of the polymer insulator with a ceramic and a glass insulator can be known if operated in tropical climatic environment.The methods used wer…
Surface plasmon resonance, ellipsometry, and the quartz crystal microbalance are surface-sensitive techniques that provide valuable information of optical and mechanical properties of interfaces. They all are considered to be macroscopic techniques in the sense that they supply global parameters-such as refractive ind…
