Scientists watch quantum dots 'breathe' in response to stress

Researchers watched nanoscale semiconductor crystals expand and shrink in response to powerful pulses of laser light. This ultrafast 'breathing' provides new insight about how such tiny structures change shape as they start to melt - information that can help guide researchers in tailoring their use for a range of applications.
