On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability

28 Sep 2005 | Online Presentations | Contributor(s): Muhammad A. Alam

In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked...

Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons

03 Oct 2005 | Online Presentations | Contributor(s): Vladimir M. Shalaev

The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate...
