Mechanical strain is one of the most common tools used to tailor the properties of materials. In piezoelectric materials, stretching or compressing a crystal generates an electrical polarization. In ...

Scientists have created an “electron lighthouse” that uses laser light to launch and steer electrons through a semiconductor without an applied electrical field. The quantum effect could eventually ...

In a breakthrough study, physicists at the University of Michigan (U-M) have illuminated new physics by developing an ...

Modern imaging is increasingly expected to do more than “take a picture.” In many real-world scenarios, what matters is not only the overall brightness of an object, but also where its boundaries, ...
