After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.
A research study on low noise and high-performance transistors led by Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with researchers at Purdue University, was recently ...
Scientists at the U.S. Naval Research Laboratory (NRL) have fabricated a bilayer structure comprised of two different monolayer materials, and observed a unique electronic state formed by the interaction between these two ...
In 2010, the Nobel Prize in Physics went to the discoverers of graphene. A single layer of carbon atoms, graphene possesses properties that are ideal for a host of applications. Among researchers, graphene has been the hottest ...
Sheet-like materials can have intriguing properties that could benefit devices from flexible electronics to solar cells. Researchers think they can customize the properties of these materials by using light pulses to rapidly ...
Physicists at the University of California, Riverside have developed a photodetector - a device that senses light - by combining two distinct inorganic materials and producing quantum mechanical processes that could revolutionize ...
Optical sensors operating in the near infrared (NIR) are important for applications in imaging, photodetectors, and biological sensors. Notably, recent reports on the synthesis of high quality, large areas of graphene has ...
Zhe Fei pointed to the bright and dark vertical lines running across his computer screen. This nano-image, he explained, shows the waves associated with a half-light, half-matter quasiparticle moving inside a semiconductor.
Common sense might dictate that for an object to move from one point to another, it must go through all the points on the path.
Could adding defects make a good material even better? Scientists have found that linear defects in a promising thin film create one-atom-thick metallic wires. These wires cross the otherwise intact material, offering a way ...
