Non-centrosymmetric halide perovskites are a class of semiconducting material containing a structural asymmetry with potentially transformative implications for several major industries.
Jian Shi, Ph.D., associate professor in both the Department of Materials Science and Engineering and the Department of Physics, Applied Physics, and Astronomy at Rensselaer Polytechnic Institute (RPI), has been selected for the Simons Foundation's Pivot Fellowship.
TROY, N.Y. — Optoelectronic materials that are capable of converting the energy of light into electricity, and electricity into light, have promising applications as light-emitting, energy-harvesting, and sensing technologies. However, devices made of these materials are often plagued by inefficiency, losing significant useful energy as heat. To break the current limits of efficiency, new principles of light-electricity conversion are needed.
TROY, N.Y. — If new and promising semiconductor materials are to make it into our phones, computers, and other increasingly capable electronics, researchers must obtain greater control over how those materials function. In an article published today in Science Advances, Rensselaer Polytechnic Institute researchers detailed how they designed and synthesized a unique material with controllable capabilities that make it very promising for future electronics.
A promising semiconductor material could be improved if flaws previously thought irrelevant to performance are reduced, according to research published today in Nature Communications.
The use of pressure to alter semiconductor properties is showing increasing promise in applications such as high-performance infrared sensors and energy conversion devices.
It’s a small change that makes a big difference. Researchers have developed a method that uses a one-degree change in temperature to alter the color of light that a semiconductor emits.
