  1. Modeling of nanotechnology: nano-electronics from quantum theory Prof. Hong Guo’s research group: Dongping Liu & Jesse Maassen Physics department McGill University 1 nanometer (nm) = 0.000000001 meter 1 nm Copper

  2. Current Device Electrode Electrode Modeling of nanotechnology: nano-electronics from quantum theory Our focus : Applying quantum theory to study current flow in nano-scale systems. This method represents the state-of-the-art.

  3. Impact of our research Understand and improve : • Transistors (1 billion/chip) • Energy applications • Solar cells • Hydrogen production & storage • Thermoelectrics • Memory devices (hard drives, …)

  4. Engineering Science quantum mechanics Physics CLUMEQ atomic simulations materials, physics device modeling < 50nm (1000 atoms) large scale device modeling device parameters bigger smaller How does CLUMEQ influence our research ? 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.

  5. How does CLUMEQ influence our research ? An example: Typical calculations reach ~ 100-500 atoms. World record = 1000 atoms. With CLUMEQ, we attained more than 10000atoms! 20 nm

  6. 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. ?
