Microstructural and Compositional Characterization of Thin-Film Semiconductor Materials by Transmisrties. Some, such as secondary ion mass spectrometry (SIMS) and the electrical techniques, can be combined with profiling to probe properties as a function of depth normal to the epitaxial layers, but at distances 10 ≲nm (100Å) resolution limits begin to be approached.

Serendipity, Punctuatedma industry, the invention of spread-spectrum and frequency-hopping communications, nuclear space propulsion, and oceanography. The unlikely chain of events began with the invention of a secure military communications system by a Viennese motion picture actress (1942). A first evaluation of the nove
