High reflectivity and low loss mirrors are very much essential for state-of art sensors like Ring Laser Gyroscopes widely used navigation of moving platforms. Surface scattering is the main source high reflectivity. also lead to coupling back reflected light leading dead band optical at input rotation. Super polished glass substrates have been prepared from expansion ceramic material. roughness...

Electron beam deposition ~EBD! provides an inexpensive way to fabricate nanostructures of various materials in a scanning electron microscope ~SEM!. However, the purity of metals deposited from an organometallic precursor gas is impaired by simultaneously deposited carbon coming both from the organometallic molecule and the residual contamination gas in the SEM chamber. We discuss carbon-contam...

In an electron beam sustained discharge Xenon laser the discharge energy deposition has been varied in order to investigate the saturation effect on the Xenon laser. The current density of the electron beam is varied separately in the range of 0.1-2.7 A/cmz to obtain optimized discharge excitation conditions as a function of electron beam current density and gas pressure. An optimal fractional ...

Platinum-carbon nanostructures deposited via electron beam induced deposition from MeCpPt(IV)Me3 are purified during a post-deposition electron exposure treatment in a localized oxygen ambient at room temperature. Time-dependent studies demonstrate that the process occurs from the top-down. Electron beam energy and current studies demonstrate that the process is controlled by a confluence of th...

Techniques for characterization and methods for fabrication at the nano-scale are becoming more powerful, giving new insights into the spatial relationships between nanostructures and greater control over their development. A case in point is the application of state-of-the-art focused ion beam technology (FIB), in combination with high-performance scanning electron microscopy (SEM), giving the...

The resolution of lithography techniques needs to be extended beyond their current limits to continue the trend of miniaturization and enable new applications. But what is the ultimate spatial resolution? It is known that single atoms can be imaged with a highly focused electron beam. Can single atoms also be written with an electron beam? We verify this with focused electron-beam-induced depos...

Highlights Focused Ion Beam Lithography is a very powerful technique for directly writing patterns on many substrates, it is a mask-less and resist-less technique that allows a very wide range of applications, providing a resolution down to 10 nm. Joined to the Electron Beam Lithography and the Gas Deposition System it became a very versatile tool for many fabrication processes. Using a dual-be...

Electron-beam-induced deposition ~EBID! is a potentially fast and resistless deposition technique which might overcome the fundamental resolution limits of conventional electron-beam lithography. We advance the understanding of the EBID process by simulating the structure growth. The merit of our model is that it explains the shapes of structures grown by EBID quantitatively. It also predicts t...
