Article Synopsis
  • Meter-scale, thin lightsail spacecraft could revolutionize space exploration by using high-power lasers for propulsion, but they present significant engineering challenges.
  • Researchers developed a complex simulator to analyze the design of flexible lightsails, ensuring they can maintain stability during acceleration without collapsing.
  • Innovations using silicon nitride membranes show promise for creating stable, efficient lightsails that could be manufactured with current microfabrication techniques, potentially enabling travel to interstellar distances.

Knowledge of the vibrational structure of a semiconductor is essential for explaining its optical and electronic properties and enabling optimized materials selection for optoelectronic devices. However, measurement of the vibrational density of states of nanomaterials is challenging. Here, using the example of colloidal nanocrystals (quantum dots), we show that the vibrational density of states of nanomaterials can be accurately and efficiently measured with inelastic X-ray scattering (IXS).
