Self-Heating and Scaling of Silicon Nano-Transistors
Online Presentations | 05 Aug 2004 | Contributor(s):: Eric Pop
The most often cited technological roadblock of nanoscale electronics is the "power problem," i.e. power densities and device temperatures reaching levels that will prevent their reliable operation. Technology roadmap (ITRS) requirements are expected to lead to more heat dissipation problems,...
