Biography Summary

Dayan Ban is an Associate Professor in Electrical and Computer Engineering and is a researcher at the Waterloo Institute for Nanotechnology.

His expertise lies in the conversion of near infra-red light directly to visible light, design and fabrication of high-performance quantum devices and the development of ultra-sensitive surface plasmon sensors.

Professor Ban successfully improved the efficiency of hybrid organic/inorganic devices by more than one order of magnitude and applied time-domain terahertz spectroscopy to study the device physics of terahertz quantum cascade lasers. Professor Ban’s research has also accomplished the fabrication of prototype hybrid organic/inorganic devices by direct tandem integration and the study of the effects of interfacial states on device performance. These devices are responsible for the conversion of near-infrared light directly to visible light (green) at room temperature.

Professor Ban pioneered the development of new methods in scanning probe microscopy to observe, with nanometric spatial resolution, two-dimensional profiles of conductivity and potential inside actively-driven lasers. He also resolved the nanoscopic reason for anomalously high series resistance encountered in ridge waveguide lasers. In addition, Professor Ban reported the first direct experimental observation of electron overbarrier leakage in operating buried heterostructure multi-quantum-well –lasers. His work has provided the first experimental visualization of the inner workings of operating semiconductor lasers, and has also provided a platform for enabling tools for quantum semiconductor device and nanotechnology research.
