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 and energy devices with enhanced properties that exceed those of the “normal” cubic form of silicon used today.

When it comes to earthquakes, seismologists know best. But deep-focus earthquakes—those that occur between 300 and 700 km below the surface—have been a mystery to science for a century. Over the years, many scientists have suggested different answers to this problem. Still, the deep Earth is impossible to study directly, so the earthquakes kept their secrets until a group of scientists at the Earth and Planets Laboratory teamed up to crack the case.

Unlike the cicadas who go pretty much unnoticed during their time underground, EPL staff have been quite visible over the last year as they turn datasets acquired pre-pandemic into publications. As is typical of the work pursued by EPL scientists, the discoveries range from the deep Earth to distant stars.
