What to know about Stressed crystal creates nanoscale patterns on chip materials at room temperature

Researchers at Rice University have developed a technique using alpha-molybdenum trioxide crystals to create nanoscale patterns on hard materials like silica at room temperature. This method utilizes electron beam irradiation to induce stress-based wrinkles, potentially simplifying the fabrication of photonic and optoelectronic devices.
