When an electron beam impinges on a solid surface, it loses energy primarily by electron-electron interactions.

In those interactions, the energy gained by electrons in the solid is often sufficient to ionize them; the electrons thus ionized are called secondary electrons SE. The interactions of a primary electron with the solid are classed as elastic energy-conserving and inelastic energy non-conserving.

In the latter case, energy fails to be conserved in the sense that, while total energy is conserved, energy is transferred from one subsystem typically the primary electron to another the solid. It is important to recognize that the simpler processes one imagines are typically elastic.

For example, if one regards the solid simply as a rigid electrostatic potential, then almost no energy is lost by the primary electron: It is thus clear that inelastic processes--and energy loss by the primary electron--require recoil--some movement of the electrostatic potential generated by the solid.

There is a more roundabout intuitive way to see this, which demonstrates in a small way the unity of physical law. Edexcel history coursework mark schemes energy is lost by the primary electron, then the energy lost must be taken up by the solid.

Since the potential energy of the solid is determined by the positions of its constituents, it is clear that neither the potential nor the kinetic energy can change unless some part of the solid moves. A junction in a bipolar junction transistor BJT between emitter E and base regions.

By some measures, the best version of this is the famous eleventh edition first half published December ; second half six months later. It is available free online in increasingly readable form it is slowly being converted from badly OCR 'ed versions.

The modern online version is available mostly by subscription. The beginnings of articles are available as a tease. I can't quite put my finger on the reason, but the online edition of the modern EB feels anti-intuitive and hard to use.

The information is scattered in packets that don't connect very well or form a coherent narrative. Kinda like this glossary. The eleventh edition, on the other hand, is an object of veneration. They did get a lot of very good contributors, famous experts in their fields: This optimistic spirit was reflected later in the year [, marking the th anniversary of the first edition] by the publication of a full-length history called The Great EB, which presented an exhaustive account of the Encyclopaedia's growth and financial history.

The author of this skillful exercise in public relations was Herman Kogan, a former Chicago newspaperman who was subsequently appointed Director of Company Relations for the Britannica. The early parts of his book were animated by a critical spirit, but the closing portion merely offered a glowing description of the Company's editorial and sales policies.

Despite this defect, The Great EB is a useful historical work because it was compiled from the Company's private archives. It supplied a great deal of material for this [third] chapter--and its quasi-official character was emphasized by its publication by the University of Chicago Press.

Incidentally, I've decided to dedicate this entry to the memory of my cousin Rita Schaeffer, because she used to sell the Britannica. Here's another family connection: Hard to believe we could be related, huh?

Anyway, one prize she won was a Britannica. This sort of public relations co-promotion has long been a big thing for the EB. My presence in D. Then again, it was never an unimportant part either.Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years.
