An international team of researchers have used a unique tool inserted into an electron microscope to create a transistor that's 25,000 times smaller than the width of a human hair.
Direct band gap GeSn alloys have emerged as a promising group-IV gain material for low-cost infrared laser manufacturing. They face major issues like high threshold power, and low lasing temperature that hinder their integration ...
Perovskite solar cells are in many ways already as efficient as conventional crystalline silicon-based solar cells; perovskite has the added benefit of being much more cost-effective than its silicon counterpart. Perovskites ...
A team of physicists at CU Boulder has solved the mystery behind a perplexing phenomenon in the nano realm: why some ultra-small heat sources cool down faster if you pack them closer together. The findings, published today ...
Size matters when it comes to sorting biological materials. From identifying pathogens to screening for drug treatments, the ability to quickly identify and separate particles based on their size is an increasingly important ...
We might imagine crystals to be perfect structures, but they are, in fact, often plagued with "defects." Curiously enough, such defects often appear due to atoms undergoing reorganization to lower the energy of the system ...
Curved imagers that can adjust their shape could have many valuable applications, for instance, aiding the development of more advanced medical imaging tools and cameras. Most existing flexible curvy imagers, however, are ...
Scientists of Tomsk Polytechnic University jointly with colleagues from Spanish universities have offered a simple method how to enhance the responsivity of terahertz radiation detectors by 3.5 times using a small Teflon ...
A team led by Carnegie's Thomas Shiell and Timothy Strobel developed a new method for synthesizing a novel crystalline form of silicon with a hexagonal structure that could potentially be used to create next-generation electronic ...
Scientists are certain that dark matter exists. Yet, after more than 50 years of searching, they still have no direct evidence for the mysterious substance.
