Silicon Alley and the idea of New York City as a dot-com center. In 1997, over 200 members and leaders of Silicon Alley joined NYC entrepreneurs, Andrew Rasiej and Cecilia Pagkalinawan to help wire Washington Irving High School to the Internet. This response and the Department of Education's growing need for technology integration marked the birth of Making Opportunities for Upgrading Schools and Education (MOUSE), an organization that today serves tens of thousands of underserved youth in schools in five states and over 20 countries. The rapid growth of internet companies during the 1990s, known as the Dot-com bubble, came to a
Polycrystalline silicon grain boundaries, see figure 1. The resistivity, mobility, and free-carrier concentration in monocrystalline silicon vary with doping concentration of the single crystal silicon. Whereas the doping of polycrystalline silicon does have an effect on the resistivity, mobility, and free-carrier concentration, these properties strongly depend on the polycrystalline grain size, which is a physical parameter that the material scientist can manipulate. Through the methods of crystallization to form polycrystalline silicon, an engineer can control the size of the polycrystalline grains which will vary the physical properties of the material. The use of polycrystalline silicon in the production of solar cells requires
