Researchers from the Low Energy Electronic Systems (LEES) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore together with Massachusetts Institute of Technology (MIT) and National University of Singapore (NUS), have discovered a new way to control light emission from materials.

Controlling the has been the driving force behind most modern technologies—from solar panels, computers, smart vehicles or life-saving hospital equipment. But materials properties have traditionally been adjusted based on their composition, structure, and sometimes size, and most practical devices that produce or generate light use layers of materials of different compositions that can often be difficult to grow.

The breakthrough by SMART researchers and their collaborators offers a new paradigm-shifting approach to tune the optical properties of technologically-relevant materials by changing the twist angle between stacked films, at room temperature. Their findings could have a huge impact on various applications in the medical, biological, and quantum information fields. The team explain their research in a paper titled "Tunable Optical Properties of Thin Films Controlled by the Interface Twist Angle" recently published in the prestigious journal Nano Letters.
