A crystalline silicon string played with hours-long sustain

When you tension a guitar string, you change its resonant frequencies and tune the pitch of the notes you can play on it. Similarly, a nanoscale string will perform faster oscillations (in the radiofrequency, megahertz band) by increasing the tension. However, when the aspect ratio... click to read more
