Document Summary
Conductivity of materials: eletricity can flow freely through a solid if there are free valence, transistors form the basic building blocks of all computer hardware electrons in outter layer after the solid is formed. Allowed logical devices modern computer: elements" conductivity depending on # eletrons in the it"s valence, used for applications such as amplification, switching and digital logic shell and orbit of the valence shell design. Where do transistors fit: logic gate (made from) transistors (based on) pn- junctions (made from) semiconductors. Pn-junctions = a junction made from 2 materials a p and a n . Eletroncs entering a material on one side traverse through the elements through the valence shell. By exchanging positions with valence electrons of elements exit electron != initial electron. Elements w/ full valence shell = not conductors. Higher outter orbit better flow b/c less attraction force from: electricity is caused by the flow of charged particles, usually electrons protons in neucleus.
