In semiconductor manufacturing, what is small today will seem large tomorrow, which is true as much for the wavelengths required to make the chips as...
A major issue with gallium-nitride LEDs is that, although they efficiently generate short-wavelength photons, the high refractive index of GaN (n =...
Raman spectroscopy is useful for applications where high-specificity biological or chemical sensing is required. Unfortunately, sensitive detection...
Using ultrafast infrared spectroscopy, researchers at Pennsylvania State University in University Park have observed electrons moving in real time...
What you can’t see can hurt you — at least indirectly. Surface defects and cracks are among the causes of material failures in cars, aircraft and...
