Crystal Properties and Growth of Semiconductors In studying solid state electronic devices we are interested primarily in the electrical behavior of solids. However‚ we shall see in later chapters that the transport of charge through a metal or a semiconductor depends not only on the properties of the electron but also on the arrangement of atoms in the solid. In the first chapter we shall discuss some of the physical properties of semiconductors compared with other solids‚ the atomic arrangements

Have you ever heard about the “Night of Broken Glass”? Well‚ we have to call it by the original name “Kristallnacht” that’s a German word that its significance it’s literally “Crystal Night”. Now‚ what was the “Crystal Night”? In simple words “Kristallnacht” was one of the many pogroms that were to come toward the Jewish community (at first) in Germany on World War 2. In the city of Paris‚ France on November 7 1938‚ a young German-born Polish Jew called Herschel Grynszpan (Sometimes Greenspan)

deposition of uric acid crystals‚ and joint destruction if left untreated. Uric acid is a byproduct of purine metabolism. Lacking uricase‚ humans remove uric acid primarily by renal excretion. "Normally‚ uric acid dissolves in your blood and passes through your kidneys into your urine. But sometimes your body either produces too much uric acid or your kidneys excrete too little uric acid. When this happens‚ uric acid can build up‚ forming sharp‚ needle-like urate crystals in a joint or surrounding

insight review articles Optical microcavities Kerry J. Vahala California Institute of Technology‚ Mail Stop 128-95‚ Pasadena‚ California 91125‚ USA (e-mail: vahala@caltech.edu) Optical microcavities confine light to small volumes by resonant recirculation. Devices based on optical microcavities are already indispensable for a wide range of applications and studies. For example‚ microcavities made of active III–V semiconductor materials control laser emission spectra to enable long-distance

other at the first glance‚ but if you study them close‚ they actually have many similarities. One of Donatello’s best-known work portrays David after he defeated Goliath by striking him with a stone and cutting his head off with Goliath’s own sword. Donatello was the first artist that created a nude life-sized sculpture since antiquity. His bronze sculpture of David indicates that he completely mastered the classical tradition of art.
