Silicon spheres

Silicon microstructures can be categorized according to the dimensionality of the confinement. Most PL studies deal with silicon structures confined in three dimensions such dot-like structures are designated zero-dimensional (OD). An overview of size-dependent properties of silicon spheres is given in Table 6.1. Standard methods of generating such microstructures are gas-phase synthesis [Di3, Li7, Scl2], plasma CVD [Ru2, Col, Ta8] or conventional chemical synthesis [Mal5]. [Pg.165]

This chapter opened with a photo of a nearly perfect silicon sphere that is being used to determine Avogadro s number. Use your Web browser to connect to http //chemistry.brookscole.com/skoogfac/. From the Chapter Resources Menu, choose Web Works. Locate the Chapter 4 section and click on the link to the Australian National Measurement Laboratory. Read the article on Avogadro s number and the silicon kilogram. What factors limit accuracy in the determination of this number What are the present and ultimate uncertainties in the measurement of the molar mass of silicon, the number of atoms per unit cell, the mass, the volume, and the lattice parameter of silicon ... [Pg.86]

EFFECT ON POLYMER AND/OR OTHER ADDITIVES Crosslinked silicone spheres have their biggest application in polypropylene films.They lower coefficient of friction and blocking force. Spheres do not affect film clarity and have high temperature resistance. They are approved by the FDA for contact with food up to the concentration in film of 5,000 ppm. ... [Pg.175]
