Developed by a team led by Professor Mona Jarrahi, the metasurface comprises an array of MEMS units that can be opened and closed by applying a voltage. This action encodes an incoming terahertz wave into a corresponding series of zeroes or ones, ...
... so it could complement electrically conductive graphene-based nanoelectronics — for example, in the next generation of 3-D semiconductors and 3-D thermal transport devices, which could be used in nanoscale calorimeters, microelectronic processes, ...
Beyond all of the hype and tumult, market drivers and technological developments are converging to ensure a bright future for silicon photonics, according to the 'Silicon Photonics 2014' report from Yole Développement. Indeed, although the silicon ...
Position sensing with a subnanometre resolution has long been an exclusive domain of optical interferometry. Operating over bandwidths as high as a few hundred kHz has meant that progress on alternative non-optical, non-contact sensors has been ...
“Optical explosive sensors are very sensitive and compact,” said Zhang, who is also director of the Materials Science Division at the Lawrence Berkeley National Laboratory and director of the National Science Foundation Nanoscale Science and ...
