Explores the relationships which exist between the performance of electrical, optical, and magnetic devices and the microstructural characteristics of the materials from which they are constructed. Features a device-motivated approach which places strong emphasis on emerging technologies. Device applications of physical phenomena are considered, including electrical conductivity and doping, transistors, photodectors and photovoltaics, luminescence, light emitting diodes, lasers, optical phenomena, photonics, ferromagnetism, and magnetoresistance.

This is a comprehensive science textbook for Grade 12. You can download or read it on-line on your mobile phone, computer or iPad. Every chapter comes with video lessons and explanations which help bring the ideas and concepts to life. Summary presentations at the end of every chapter offer an overview of the content covered, with key points highlighted for easy revision. Topics covered are: organic molecules, organic chemistry, organic macromolecules, polymers, reaction rates, electrochemical reactions, the chemical industry, motion in two dimensions, mechanical properties of matter, work, energy and power, doppler effect, colour, 2D and 3D wavefronts, wave nature of matter, electrodynamics, electronics, electromagnetic radiation, optical phenomena and properties of matter, light, photoelectric effect, lasers. This book is based upon the original Free High School Science Text series.

This OLogy activity challenges students to find nine inventions that Einstein's ideas helped to create. The activity begins with an illustration of Al's Junk Shop. Mixed in with his junk are a Global Positioning System, CD player, computer, calculator, scanner, laser pointer, TV, and representations of both laser surgery and nuclear energy. After making a mental list of their nine choices, students can click to a second page to check their answers. Each invention has a rollover note about how Einstein's ideas helped pave the way for its creation. Alternately, the first page could be printed and used as a handout for an offline activity.

What is the difference between an LED and a solid state laser? There are some differences, but both devices operate on the same principle of having excess electrons in the conduction band of a semiconductor, and arranging it so that the electrons recombine with holes in a radiative fashion, giving off light in the process. What is different about a laser?

Scanning Probe Microscopy is an important tool for scientists and engineers. A classroom analogue constructed using Lego(R) building blocks is an effective way to represent how these tools work and to interpret the images produced by them. Background information for building a Lego(R) AFM and SPM are shown. Two laboratory activities are suggested, complete with advanced set-up information, pre-laboratory discussion, laboratory directions, and post-laboratory discussion. Instructions on making Surface Plots are included for Excel PRE 2007. More recent releases of Microsoft Excel no longer have this feature.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they are introduced to Einstein's life and work with four engaging and kid-friendly areas. Equation Invasion, a look at the world's most famous equation about the relationship between energy and mass. Web Master, the scientists whose ideas and discoveries shaped Einstein's career. Light the Way, an introduction to "the fastest thing in the universe" and the waves it travels in. Everyday Einstein: LASERS, a comic strip that illustrates how Einstein's work led to the development of lasers.
