Tong Leung's laboratory is one of the very few multidisciplinary laboratories in Canada. His mission is to develop a basic understanding of radiation-matter interactions for applications in the research and design of new molecular and nanoscale materials.

The laboratory is fully equipped with several electron impact and surface science systems for studying novel processes on silicon single-crystal surfaces, and novel nanostructured materials. The laboratory also houses the premier materials research facility, Waterloo Advanced Technology Lab (WATLab), in Canada's Technology Triangle, equipped with a wide range of state-of-the-art surface and nanomaterials research tools in microscopy (HR-XRD, SEM, EDX, OIM, AFM,VT-SPM, HIM), spectromicroscopy (Imaging ESCA, SAM, UPS, SIMS, Auger Microprobe, optical microscopy fleet), fabrication (ECD, CVD, MBE, PLD), lithography (EBL,Nanoman, IBL), and rapid prototyping (for bottom-up device manufacturing) for conducting exploratory studies in all emerging areas of nanotechnology and nanosciences.

As the home of one of the very few helium ion microscopes and ion beam lithography systems in the world, WATLab offers sub-nanometer surface imaging and novel rapid prototyping capability second to none in the world.
