A new way of making LEDs could see household lighting bills reduced by up to 75% within five years. Gallium Nitride (GaN), a man-made semiconductor used to make LEDs (light emitting diodes), emits bri...
Superconductivity was recently observed in iron-arsenic-based compounds with a superconducting transition temperature (T c) as high as 56 K, naturally raising comparisons with the high-T c copper oxid...
Remarkable new tools that spotlight individual cellular molecules are transforming biomedical research. Scientists at the Gruss Lipper Biophotonics Center at the Albert Einstein College of Medicine of...
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. ...
Terahertz cascade lasers are a new family of semi-conductor lasers which emit in the frequency range of the terahertz, or 1012 hertz. Because of their potential applications, they currently raise cons...
德国和西班牙两国科研小组合作,利用红外线纳米近场显微镜发明了一种无干扰检测纳米半导体材料张力的新方法,这一新方法为科学家研究半导体材料的物理性能,以及测量纳米级半导体元器件的性能提供了新的可能。
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved inf...
Using two simultaneous light-based probing techniques at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, a team of researchers has illuminated important details about a class of...
