Properties of Ultrathin Amorphous Silicon Nitride Films on III-V Semiconductors
Properties of ultrathin (~ 10nm) silicon nitride films on single crystal Si, InP and GaAs have been studied using Raman spectroscopy, medium energy ion scattering (MEIS), variable-energy positron annihilation ...

A Variational Principle, the Finite Element Method, and Optimal Structural Design for Given Deflection
General Remarks. The optimal design of continuous or pieeewise continuous structural systems can be approached along two avenues. On one hand the system can be discretized at the outset and a seq...

Minimum-weight design of elastic sandwich beams with deflection constraints
In this paper, minimum-weight design of an elastic sandwich beam with a prescribed deflection constraint at a given point is investigated. The analysis is based on geometrical considerations using then-dimensiona...
