Graphen is probably the most promising materiak in this nano vision of IBM and others (EU has funded huge research effort in this space)...I wonder how long before graphene is used in commercial applications...5 years? 10? 20?
liangchen; Its purpose is and what it is really all about is.. "More specifically, we are studying functional molecules where electrical resistance can be switched when the molecule is contacted by two electrodes in a two-terminal device. In contrast to many other devices where a third electrode is needed, the two-terminal concept enables ultimate scaling and therefore the highest integration densities for memory applications."
It's about finding a way of manipulating structure at the atomic, molecular or bonding level to create the ultimate memory device. Consider it phase change memory (PCM) at the atomic or molecular level, where the phase (P) may not be the one we have all become used to in today's PCM which will be considered its stone-age antecedent.
I would guess they consider these devices will be so sensitive to noise that they need a quiet room rather than a box.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
