    Calculation of electrical mean free path in nanomaterials?

    How does one roughly predict the mean free path for electrical conduction in a nanostructure at different temperatures and under different electrical conditions such as different voltages and amperages based on the composition and dimensions of the structure? For instance in carbon single and...

    Are real nano wires like the ones in Larry Niven?

    Hi, this is my VERY FIRST post so if I've made a bundle of noob mistakes accept my pre-emptive mea culpa. I did read and like the rules. I have seen some stories in Phys.org about nano wires and I immediately thought of the nano wires in Larry Niven Known Space milieu which can cut right through...

    Future of Moore's Law, Physics, and Nano Devices

    Hi! The other day, I read about Moore's Law. To me it seems a miracle how one could predict in 1965 that the number of transistors would double every two years. However, there has to be an end to this exponential growth due to limits of nano technology, fabrication of semiconductors...
