Hybrid organic or inorganic halide perovskites are a unique class of solar cell materials that break some of the material design rules that have been in place for over 30 years. For instance, they can achieve an extraordinarily ...
Anyone who's ever played the drums, tuned a guitar, or even made a wine glass "sing" by circling a finger along its edge knows about resonance. Acoustic resonators, like the cavity of a drum or a half-full wine glass, naturally ...

Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both ...
Manipulating nanoscale light in scanning tunneling microscope junctions is attained by nanofabrication of gold tips using a focused ion beam technique. Researchers at Fritz-Haber Institute, Berlin, Germany, demonstrated that ...

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...
When exposed to intense laser pulses, the magnetization of a material can be manipulated very fast. Fundamentally, magnetization is connected to the angular momentum of the electrons in the material. A team of researchers ...
