Microscale BTS sculptured by electron beam

Channel estimation study of CDMA downlink for fixed beam BTS

Sculptured Layer-by-Layer Films

The precise assembly of nanostructured materials into two (2D) and three-dimensional (3D) periodic microscopic arrays is achieved by employing various assembling technologies such as microparticle self-organization, photolithography, holographic lithography, selective chemical etching, ink printing, laser-based polymerization, selective responsive grafting, and inversion of bilayers. Soft litho...

Microscale Metallography Using Focused Ion Beam

Microstructural examination can provide a rich tapestry of information about the processing and application history of a metal component. For this reason, microstructural characterization is a fundamental tool for failure analysis of these components. To reduce costs and accommodate demands for smaller packaging, many applications currently use metallic components where the critical dimensions ...

Fabrication of nanoscale Ga balls via a Coulomb explosion of microscale silica-covered Ga balls by TEM electron-beam irradiation

Nanoscale Ga particles down to 5 nm were fabricated by an explosion via an in situ electron-beam irradiation on microscale silica-covered Ga balls in a transmission electron microscope. The explosion is confirmed to be a Coulomb explosion because it occurs on the surface rather than in the whole body of the insulating silica-covered Ga micro-balls, and on the pure Ga nano-balls on the edge of c...

Blending of nanoscale and microscale in uniform large–area sculptured thin–film architectures

The combination of large thickness (> 3 μm), large–area uniformity (75 mm diameter), high growth rate (up to 0.4 μm/min) in assemblies of complex–shaped nanowires on lithographically defined patterns has been achieved for the first time. The nanoscale and the microscale have thus been blended together in sculptured thin films with transverse architectures. SiOx (x ≈ 2) nanowires were grown by e...
