Dr. Stefan Strauf, Assistant Professor of Physics and Engineering Physics at Stevens Institute of Technology, has been honored by the National Science Foundation (NSF) with the prestigious CAREER Award. One of the most competitive programs offered by the NSF, the CAREER Award supports early career development of faculty in the sciences who are most likely to become leading researchers and teachers. The awards provide a financial stipend to support research activity over the course of five years.
The objective of Dr. Strauf's awarded research is to address the problem of scalability of semiconductor quantum photonic devices, which are currently limited by the inherently random nucleation process of self-assembled quantum dots. Essentially nanoscale crystals, quantum dots possess many useful physical properties and in particular the ability to emit photons one by one resulting in quantum light emission. Quantum photonic devices are expected to become building blocks for a new generation of technologies able to process quantum information, which enables performing tasks that would be unachievable with classical computers, such as unconditionally secure transmission of information.
"Dr. Strauf's well-deserved recognition by the NSF emphasizes the potential impact of this disruptive technology breakthrough," commends Dr. Michael Bruno, Dean of the Charles V. Schaefer, Jr. School of Engineering and Science. "His achievement epitomizes Stevens investment in innovative nanotechnology research that will have profound implications for the national and global economy."
Dr. Strauf's research utilizes top-down fabrication approaches to create novel "vertical quantum dots" by etching them from a semiconductor wafer. These vertical quantum dots can be precisely positioned in large quantity with respect to other nanostructures such as photonic crystal cavities and waveguides. Etching can cause challenges such as non-radiative recombination, in which
