How does CLUMEQ influence our research ? large scale device modeling device parameters atomic simulations materials, physics quantum mechanics Physics device modeling < 50nm (1000 atoms) CLUMEQ Science Engineering smaller bigger With CLUMEQ, there’s a qualitative change in the problems that we can treat. Our techniques can be applied to new unexplored, commercially relevant, hi-tech problems.

How does CLUMEQ influence our research ? An example: Typical calculations reach ~ atoms. World record = 1000 atoms. With CLUMEQ, we attained more than atoms! 20 nm

Take home message ? Nanotechnology is poised to enter the industrial world. It will impact all aspects of modern technology (electronics, energy, medicine,…). With our local expertise combined with resources like CLUMEQ, Québec will be at the forefront of this technological & commercial revolution.
