Multiple Wavelength LED on Monolithic QW Structure

A monolithically integrated multi-wavelength LED based on selective dielectric cap intermixing is investigated experimentally. The proposed LED emits radiation with multiple wavelength peaks from one compact easy to fabricate quantum well (QW) structure. Each wavelength has an independent emission power control, allowing the LED to radiate one or more wavelengths simultaneously. The LED materia...

The volume is a clearly printed and as well illustrated as ever, but is printed on fine thin paper, so that the bulk of the book is reduced. The general index is particularly well done, and there are no less than 42 plates and 200 other illustrations. A useful glossary of new ter...

Paul Erdös (1913-1996)

On October 18, 1996, hundreds of people, including many mathematicians, gathered at Kerepesi Cemetery in Budapest to pay their last respects to Paul Erdős. If there was one theme suggested by the farewell orations, it was that the world of mathematics had lost a legend, one of its great representatives. On October 21, 1996, in accordance with his last wishes, Paul Erdős’ ashes were buried in hi...
