Anne Itsuno, graduate student in the Electrical Engineering program, received a prestigious NSF Graduate Research Fellowship for her research in infrared photodetector devices. Itsuno works withProf. Jamie Phillips.

When asked about her research, Itsuno responded, “My research is focused on II-VI compound HgCdTe-based infrared photodetector devices with applications in thermal imaging and detection. I am involved in both device modeling and experimental work. Previously, I worked on a dopant diffusion study applicable to higher operating temperature (HOT) infrared detectors and modeled long wavelength infrared and mid-wavelength infrared HgCdTe detectors to compare performance metrics between conventional double layer planar heterostructure (DLPH) and HOT devices.”

“I am currently focused on simulating very long wavelength infrared (VLWIR) detectors with potential space applications. I plan to be involved with developing optimal optical structures to enhance VLWIR device performance.”

The National Science Foundation’s Graduate Research Fellowship Program (GRFP) recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master’s and doctoral degrees in the U.S. and abroad.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
