Electronics From the Bottom Up: a view of conductance
Online Presentations | 17 Aug 2007 | Contributor(s):: Supriyo Datta
Resistance is one of the first concepts an electrical engineer learns, but things get interesting at the nanoscale. Experimentalists have found that no matter how short the resistor is, its resistance cannot drop below a fundamental lower limit. They also found that resistance increases in...

Electronics From the Bottom Up: top-down/bottom-up views of length
Online Presentations | 17 Aug 2007 | Contributor(s):: Muhammad A. Alam
When devices get small stochastic effects become important. Random dopant effects lead to uncertainties in a MOSFET’s threshold voltage and gate oxides breakdown is a random process. Even a concept as simple as “channel length” becomes uncertain. This short (20 min) talk, a footnote to the...
