Mechanism of discrete breather excitation in driven micro-mechanical cantilever arrays

Thermo-mechanical optimization of thermally actuated cantilever arrays

Scanning probe lithography (SPL) is an emerging method of producing sub 50-nm features for semiconductor applications. A new variation of this process known as Dip Pen Nanolithography (DPN) expands the range of SPL capabilities to include depositing organic and biological macromolecules with nanometer precision. Recent work has been underway to implement DPN as parallel process by employing clo...

SiGeC Cantilever Micro Cooler

The fabrication and characterization of SiGeC cantilever microcoolers are described. Silicon on insulator (SOI) was used as the substrate, and two layers of 3 μm p-SiGe0.07C0.0075 and 1.14 μm n-SiGe0.07C0.0075 lattice matched to silicon were grown using molecular beam epitaxy. The uni couple cooler was fabricated using conventional integrated circuit (IC) processing, and the cantilever structur...

Spurious-free cantilever excitation in liquid by piezoactuator with flexure drive mechanism.

We have developed a cantilever holder for spurious-free cantilever excitation in liquid by piezoactuator. In the holder, generation and propagation of an acoustic wave are suppressed by "acoustic barriers," i.e., boundaries between two materials having significantly different acoustic impedance while cantilever vibration is excited by "flexure drive mechanism" utilizing elastic deformation of a...

Electronically driven adsorbate excitation mechanism in femtosecond-pulse laser desorption.

Effective breather trapping mechanism for DNA transcription.

Collective coordinate and direct numerical integration methods are applied to the analysis of a one-dimensional DNA model. A modification of the coupling constant in an extended region is found to be less selective towards the breather it can trap than an isolated impurity. Therefore it provides a possible physical mechanism for the effect of an enzyme on DNA transcription. PACS: 87.10.+e, 03.4...
