Use of RBT unreleased NEM resonator models for device (topological) optimization
Papers | 26 Apr 2017 | Contributor(s):: Bichoy W. Bahr
The use of Phononic Crystals (PnC) in suspended structures and microstructures, such as plates and slabs, has gained a lot of attention in the past years for the wide range of feasible applications (acoustic waveguides, acoustic insulation, acoustic cloaking) and for the easy fabrication...

Optical Absorption in B13 Cluster: A Time-dependent Density Functional Approach
Papers | 19 Feb 2013 | Contributor(s):: Ravindra L Shinde, Meenakshi Tayade
The linear optical absorption spectra of three isomers of planar boron cluster B13 are calculated using time dependent spin-polarized density functional approach. The geometries of these cluster are optimized at the B3LYP/6-311+G* level of theory. Even though the isomers are almost degenerate,...

Optical absorption in boron clusters B6 and B6+ : A first principles configuration interaction approach
Papers | 07 Sep 2012 | Contributor(s):: Ravindra L Shinde
The linear optical absorption spectra in neutral boron cluster B6 and cationic B6+ are calculated using a first principles correlated electron approach. The geometries of several low-lying isomers of these clusters were optimized at the coupled-cluster singles doubles (CCSD) level of theory. With...

Large-scale first principles configuration interaction calculations of optical absorption in boron clusters
Papers | 07 Mar 2012 | Contributor(s):: Ravindra L Shinde
We have performed systematic large-scale all-electron correlated calculations on boron clustersBn (n=2–5), to study their linear optical absorption spectra. Several possible isomers of each clus-ter were considered, and their geometries were optimized at the coupled-cluster singles doubles(CCSD)...

Functional Graded Materials architectures applied at nanoscale: thin PVD nanograded and layered coatings
Papers | 09 Oct 2008 | Contributor(s):: Vasco Teixeira
Functionally graded materials (FGM’s) are designed to achieve levels of performance superior to that of homogeneous materials by combining the desirable properties of each constituent phase. FGM’s are composite materials where the composition or the microstructure is locally varied so that a...
