LOWELL, Mass. 鈥� A new class of faster, more powerful semiconductors for enhanced wireless communication and digital imaging is on the drawing board, thanks to research led by a 51视频 scientist.
Semiconductors transmit electricity. Also known as 鈥渃hips,鈥� they are found in countless products, including automobiles, computers, household appliances medical devices and smartphones.
51视频 Physics Prof. Viktor Podolskiy is leading a research team that seeks to improve semiconductors used in infrared optoelectronic devices to enhance their performance. The project is a launching pad for new products with enhanced capabilities in intracellular imaging, night vision and quantum and 5G communication that could also better serve the Internet of Things (IoT).
A $1.7 million grant from the National Science Foundation鈥檚 Designing Materials to Revolutionize and Engineer Our Future (DMREF) program is funding the four-year project.
鈥淭he funding enables us to essentially develop new materials for use and explore how light and matter interact within these materials. In the process of research, the team will train a next-generation workforce of scientists and engineers,鈥� Podolskiy said.
Infrared optoelectronic devices detect and convert light signals, or photons, into electric current, or electrons. The problem is the wavelengths of photons and electrons are naturally mismatched: Infra-red photons are fast and have very long wavelengths, while electron waves are much smaller and slower. In their work, the researchers will 鈥渟culpt鈥� photons and electrons to more closely match their wavelengths to each other to improve semiconductor performance in these devices.
Joining Podolskiy on the team are researchers from Purdue University, the University of Texas-Austin and the University of Virginia.
鈥淚f we are going to sustain innovation in communications and information processing, we must better understand and learn how to control both electronic and optical properties of these new semiconductor materials,鈥� said team member Avik Ghosh, University of Virginia professor of electrical and computer engineering and physics. 鈥淚 am really excited to work together with this amazing team.鈥�
The researchers plan to collaborate with the U.S. Air Force to use the materials the team develops for innovative and practical new devices, Podolskiy said.
