This is a new printing of a popular text, previously published by Prentice Hall in 1994, offering a thorough introduction to the underlying physics of semiconductor devices. It begins with a review of basic solid state physics, then goes on to describe the properties of semiconductors (energy bands, the concept of effective mass, carrier concentration and conduction) in more detail. Chapters 5 & 6 are concerned with the principles of operation of the Gunn Diode and the p-n junction. The remaining chapters focus on specific devices, including the LED, the bipolar transistor, the field-effect...

Most people are familiar with the spectacular Hubble Space Telescope images - most of them in the public domain and available on the Internet. But the Hubble images, constrained by the observing program of the HST, are mainly very distant, strange objects. There are very few high-quality books of wide-field deep-sky images on the market, primarily because the major professional telescopes are scheduled for research projects and beautiful images are secondary.

Star Vistas contains many spectacular photographs that were made specifically for this book. They are unavailable...

I have recently discovered the most satisfying hobby so far, and to be frank, I have pursued quite a few hobbies in my time This one encompasses computers, optics, precision mechanics, digital image processing and artistic appreciation, and it therefore satisfies just about every major interest I have in one go. The hobby is taking photographic images of the deep-sky. I have not met anyone, so far, that has not been moved, sometimes to a great extent, by the images you will find within the pages of this book. Some people will actually admit to being frightened by the vastness of space that...
