Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet ...

Atom interferometry has emerged as a transformative approach in both fundamental physics and practical applications, utilising the wave nature of atoms to measure minute effects of gravity, rotation ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Modern semiconductor manufacturing technology has advanced rapidly. Because of this, measurement using non-contact displacement and transparent coating thickness has become very critical. Applications ...

The ESO (European Southern Observatory) has announced the successful observation of an exoplanet using optical interferometry. It's the first time an exoplanet has been "seen" in this manner and the ...

“This three-telescope interferometry is a major milestone toward directly imaging the growth phase of supermassive black holes,” said Sebastian Hoenig, a postdoctoral researcher at the UC Santa ...

Faster computer and electronic processors require smaller features for integrated circuits (IC), which in turn require smaller and smoother substrate surfaces. Chemical mechanical polishing (CMP) has ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

Some galaxies eject powerful streams of charged particles—jets—from their centers into space. The prominent jet of Messier 87 (M87) in the constellation Virgo is visible over distances of 3,000 ...
